+# TrafagSalesExporter Handoff
+
+Stand: 2026-04-15
+
+## Nachtrag 2026-04-17
+
+Der dokumentierte Stand in diesem Handoff war bei der Waehrungslogik nicht mehr aktuell.
+
+Inzwischen gilt:
+
+- Kurstabellen fuer `CurrencyExchangeRates` sind im System vorhanden
+- `Settings` enthaelt bereits eine Pflegeoberflaeche fuer Wechselkurse
+- `ExchangeRateImportService` importiert ECB-Tageskurse nach `CurrencyExchangeRates`
+- `NormalizeCurrencyCode` ist als Value-Transformation vorhanden
+- `ConvertCurrency` ist als Record-Transformation vorhanden
+- `Program.cs` registriert beide Strategien sowie `CurrencyExchangeRateService` und `ExchangeRateImportService`
+
+Wichtig:
+
+- die Roh-Auswertung im `Management Cockpit` rechnet Stand heute weiterhin bewusst **nicht** in CHF um
+- dort bleibt der Umsatz weiterhin in `Sales Currency`
+- die Waehrungsumrechnung ist aktuell Teil des allgemeinen Transformations-/Mapping-Systems, nicht der Cockpit-Rohsicht
+
+Zusatzlich wurden am 2026-04-17 fehlende Unit-Tests fuer die Waehrungslogik nachgezogen:
+
+- `CurrencyExchangeRateServiceTests`
+- `ExchangeRateImportServiceTests`
+- Erweiterungen in
+  - `TransformationStrategiesTests`
+  - `RecordTransformationServiceTests`
+  - `TransformationCatalogTests`
+
+Aktueller Teststatus nach diesem Nachtrag:
+
+```text
+dotnet test .\TrafagSalesExporter.Tests\TrafagSalesExporter.Tests.csproj --verbosity minimal
+```
+
+Ergebnis:
+
+- erfolgreich
+- `31/31` Tests gruen
+- bekannte Warnung bleibt:
+  - SAP HANA Architekturwarnung `MSB3270`
+
+## Architekturpruefung 2026-04-17
+
+Es wurde eine erneute Gesamtpruefung der Architektur gemacht, ausdruecklich ohne neue Implementierung.
+
+### Gesamturteil
+
+Die Grundrichtung ist weiterhin sinnvoll:
+
+- klare Trennung der Quellsysteme `SAP`, `BI1`, `SAGE`, `MANUAL_EXCEL`
+- zentrales fachliches Zielschema ueber `SalesRecord`
+- zentrale technische Ablage ueber `CentralSalesRecords`
+- separater Orchestrator fuer Standort- und Konsolidierungsexport
+- Transformationssystem als eigener Layer
+
+Aber:
+
+- die Architektur ist **noch nicht stabil genug**, um sie als "fertig sauber" zu betrachten
+- die groessten Risiken liegen aktuell nicht in SAP oder Waehrungen, sondern in
+  - Start-/Schema-Initialisierung
+  - Config-Import
+  - Verteilung von Logik zwischen Razor-Seiten und Services
+
+### Wichtigste Architektur-Risiken
+
+#### 1. Start-/Schema-Initialisierung ist fragil
+
+`DatabaseInitializationService` mischt derzeit:
+
+- `EnsureCreated`
+- manuelle `ALTER TABLE`-Pflege
+- FK-Reparaturlogik
+- Seeding
+- empfohlenes Regel-Seeding
+
+Das ist funktional hilfreich, aber architektonisch gefaehrlich, weil:
+
+- die App-Initialisierung dadurch viel implizite Datenmigration enthaelt
+- Verhalten schwer vorhersehbar wird
+- Fehler im Migrationspfad sofort produktive Daten treffen
+
+Wichtiger konkreter Befund aus der Pruefung:
+
+- beim Kopieren von `Sites_old` nach `Sites` ist die Spaltenreihenfolge im SQL inkonsistent
+- dadurch koennen Werte wie `ManualImportFilePath`, `SapServiceUrl`, `SapEntitySet` verschoben gespeichert werden
+- das ist eine reale Datenkorruptionsgefahr und kein reines Architekturthema
+
+### 2. Config-Import ist destruktiv und nicht atomar
+
+`ConfigTransferService.ImportJsonAsync` loescht aktuell zuerst grosse Teile der Konfiguration und Daten:
+
+- Sites
+- HanaServers
+- Transformation Rules
+- SAP-Konfiguration
+- Wechselkurse
+- sogar `CentralSalesRecords`
+
+und baut danach mit mehreren `SaveChangesAsync()`-Zwischenschritten neu auf.
+
+Risiko:
+
+- wenn der Import in der Mitte scheitert, bleibt das System teilweise geloescht zurueck
+- `CentralSalesRecords` gehoeren fachlich ohnehin nicht sauber in einen normalen Config-Import
+
+### 3. Zu viel Fach- und Persistenzlogik in Razor-Seiten
+
+`Settings.razor` und `Standorte.razor` machen aktuell sehr viel direkt:
+
+- `DbContext` oeffnen
+- Daten laden und speichern
+- Konfigurationsimport/-export anstossen
+- SAP-Refresh
+- Upload-Handling
+- Teile der Validierung / Persistenzlogik
+
+Das funktioniert momentan, fuehrt aber langfristig zu:
+
+- schwer testbarer UI-Logik
+- verstreuten Regeln
+- hoeherem Seiteneffekt-Risiko bei Erweiterungen
+
+### 4. Vertrag zwischen Orchestrator und konsolidiertem Export ist unscharf
+
+`ExportOrchestrationService` sammelt bei `ExportAllAsync` bereits `consolidatedRecords`, uebergibt sie weiter, aber `ConsolidatedExportService` ignoriert diesen Parameter und liest erneut aus `CentralSalesRecords`.
+
+Das zeigt ein offenes Architekturthema:
+
+- Soll die zentrale Datei aus dem Live-Exportlauf gebaut werden?
+- oder immer nur aus dem persistenten Read Model `CentralSalesRecords`?
+
+Aktuell ist beides halb vorhanden.
+
+### 5. Reporting-/Cockpit-Logik ist noch nicht voll verallgemeinert
+
+Bei der Pruefung wurde gesehen:
+
+- `ManagementCockpitService` enthaelt noch hartcodierte Jahreslogik fuer `2025` und `2026`
+- die Rohsicht bleibt bewusst ohne CHF-Umrechnung
+
+Das ist fuer den aktuellen Stand akzeptabel, zeigt aber:
+
+- Reporting ist noch kein voll abstrahierter fachlicher Layer
+
+## Empfohlenes Sollbild
+
+Die naechste Architektur-Stufe sollte in diese Richtung gehen:
+
+### 1. Klare Schichten
+
+- UI:
+  - Razor nur fuer Interaktion, Anzeige, Formularzustand
+- Application:
+  - Use Cases / Commands / Queries fuer Export, Config, SAP-Refresh, Wechselkurse, Standortpflege
+- Domain / Fachlogik:
+  - Transformationen, Mappingregeln, Waehrungsumrechnung, Cockpit-Berechnungen
+- Infrastructure:
+  - HANA, SAP Gateway, SQLite, SharePoint, Dateisystem
+
+### 2. Versionierte Migrationen statt manueller Start-Reparaturen
+
+Statt immer mehr Reparaturlogik beim App-Start:
+
+- Schema-Aenderungen versionieren
+- Migrationspfade testbar machen
+- Startlogik nur noch fuer minimale Bootstrap-Aufgaben behalten
+
+### 3. Config-Import als atomarer Vorgang
+
+Ziel:
+
+- alles in einer Transaktion oder bewusst in klar getrennten Phasen
+- kein halb geloeschter Zustand bei Fehlern
+- `CentralSalesRecords` aus normalem Config-Import eher herausnehmen
+
+### 4. Zentrale Export-Semantik entscheiden
+
+Explizit festlegen:
+
+- zentrale Datei immer aus `CentralSalesRecords`
+  oder
+- zentrale Datei aus dem aktuellen Export-Snapshot
+
+Danach die doppelte Semantik entfernen.
+
+## Priorisierung aus Architektursicht
+
+Wenn nach Stabilitaet priorisiert wird, dann in dieser Reihenfolge:
+
+1. `DatabaseInitializationService` / Migrationspfad absichern
+2. `ConfigTransferService.ImportJsonAsync` atomar und weniger destruktiv machen
+3. Logik aus `Settings.razor` und `Standorte.razor` in Anwendungsservices verschieben
+4. Export-Semantik fuer Konsolidierung vereinheitlichen
+5. erst danach weitere Fachfeatures wie Cockpit-CHF, Budget, Gruppenlogik
+
+## Kurzfazit
+
+Die Architektur ist nicht schlecht. Das Grundmodell traegt.
+
+Aber:
+
+- sie ist noch nicht robust genug fuer ruhigen weiteren Ausbau ohne technische Konsolidierung
+- die aktuelle Hauptgefahr liegt in Infrastruktur- und Persistenzlogik, nicht in den Fachfeatures
+
+Fuer den naechsten Einstieg nach Absturz gilt daher:
+
+1. zuerst diesen Architektur-Nachtrag lesen
+2. dann `DatabaseInitializationService` und `ConfigTransferService` als Risikobloecke ansehen
+3. neue Fachfeatures erst nach dieser technischen Konsolidierung beginnen
+
+## Nachtrag HANA-/Standort-Workflow 2026-04-17
+
+Nach der Architekturpruefung wurde der doppelte HANA-Workflow bereinigt.
+
+### Altes Problem
+
+Vorher gab es zwei konkurrierende Stellen fuer HANA-Konfiguration:
+
+- oben eine eigene `HANA Server`-Verwaltung
+- unten im Standortdialog noch einmal eine fast vollstaendige HANA-Verbindung
+
+Dadurch war unklar:
+
+- was die zentrale Wahrheit ist
+- wann ein zentraler Server geaendert wird
+- wann still ein separater Server pro Standort entsteht
+
+### Neue Logik
+
+Oben gilt jetzt:
+
+- `HANA Server` ist zentrale HANA-Konfiguration pro Quellsystem
+- aktuell relevant fuer:
+  - `BI1`
+  - `SAGE`
+
+Unten im Standort gilt jetzt:
+
+- Standort pflegt nur noch standortspezifische Daten
+  - `Schema`
+  - `TSC`
+  - `Land`
+  - `SourceSystem`
+  - optionale Username-/Password-Overrides
+- die technische HANA-Verbindung kommt aus der zentralen Konfiguration des Quellsystems
+
+### Technische Umsetzung
+
+- `HanaServer` hat jetzt zusaetzlich `SourceSystem`
+- `DatabaseInitializationService` stellt zentrale Eintraege fuer `BI1` und `SAGE` sicher
+- bestehende verknuepfte HANA-Server werden dabei moeglichst auf `BI1` / `SAGE` gemappt
+- `SiteExportService` baut HANA-Verbindungen jetzt aus der zentralen HANA-Konfiguration des Quellsystems
+- `Settings.razor` testet BI1/SAGE nicht mehr ueber einen Beispiel-Standort, sondern ueber die zentrale HANA-Konfiguration
+- `Standorte.razor` speichert im Standort fuer HANA-basierte Systeme keine eigene Vollverbindung mehr
+
+### Wichtige Konsequenz
+
+Fachlich gilt jetzt:
+
+- oben = Standardkonfiguration pro Quellsystem
+- unten = Standort + optionale Credential-Overrides
+
+Das entspricht der gewuenschten Logik:
+
+- gleiche BI1-/SAGE-Standorte koennen zentrale Verbindungswerte teilen
+- Ausnahmen koennen weiter ueber Username-/Password-Overrides reagieren
+
+### UI-Nachtrag
+
+Die frueher doppelte und dadurch verwirrende UI wurde danach auch sichtbar bereinigt.
+
+Aktueller UI-Stand:
+
+- oben heisst der Bereich jetzt klar `Zentrale HANA-Konfiguration`
+- im Standortdialog gibt es fuer HANA keine zweite technische Eingabestrecke mehr
+- dort wird nur noch die aktive Zentralverbindung angezeigt
+- Host, Port, SSL und technische Parameter werden explizit nach oben verwiesen
+- der zentrale Verbindungstest in `Settings.razor` meldet jetzt sauber die zentrale HANA-Verbindung
+
+## Nachtrag Quellsystem-Verwaltung 2026-04-17
+
+Die bisher noch hart codierten Quellsystem-Listen wurden entfernt und durch echte Stammdaten ersetzt.
+
+### Neuer Stand
+
+- neues Modell `SourceSystemDefinition`
+- Quellsysteme werden jetzt zentral in der DB gehalten statt in Razor-Arrays
+- pro Quellsystem werden gepflegt:
+  - `Code`
+  - `DisplayName`
+  - `ConnectionKind`
+  - `IsActive`
+  - `CentralUsername`
+  - `CentralPassword`
+
+### Neue GUI-Logik
+
+- `Settings.razor` enthaelt jetzt eine pflegbare Quellsystem-Tabelle
+- dort koennen Quellsysteme per GUI angelegt, bearbeitet und gespeichert werden
+- Anschlussart ist nicht mehr implizit im Code, sondern pro Quellsystem konfigurierbar
+- zentrale Zugangsdaten haengen jetzt am Quellsystem selbst
+
+### Anschlussarten
+
+Aktuell technisch vorgesehen:
+
+- `HANA`
+- `SAP_GATEWAY`
+- `MANUAL_EXCEL`
+
+Damit gilt:
+
+- HANA-Konfiguration oben in `Standorte.razor` nur noch fuer Quellsysteme mit Anschlussart `HANA`
+- Standort-Dropdown zieht seine Quellsysteme jetzt aus `SourceSystemDefinitions`
+- Transformationsregeln ziehen ihre Quellsystem-Auswahl ebenfalls aus `SourceSystemDefinitions`
+
+### Technische Umsetzung
+
+- `AppDbContext` hat jetzt `DbSet<SourceSystemDefinition>`
+- `DatabaseInitializationService` erzeugt und seedet `SourceSystemDefinitions`
+- `SiteExportService` loest zentrale Credentials jetzt ueber `SourceSystemDefinition`
+- `ConfigTransferService` exportiert/importiert jetzt auch `SourceSystemDefinitions`
+
+### Verifikation
+
+Nach dieser Umstellung geprueft:
+
+```text
+dotnet build .\TrafagSalesExporter.csproj -v minimal
+dotnet test .\TrafagSalesExporter.Tests\TrafagSalesExporter.Tests.csproj --verbosity minimal
+```
+
+Ergebnis:
+
+- Build erfolgreich
+- Tests erfolgreich
+- `31/31` Tests gruen
+
+### Bereinigung der Legacy-Credentials
+
+Danach wurden auch die alten zentralen Credential-Felder technisch bereinigt.
+
+Aktueller Stand:
+
+- `ExportSettings` enthaelt keine alten Felder mehr fuer `SapUsername`, `Bi1Username`, `SageUsername` usw.
+- der Config-Export schreibt zentrale Zugangsdaten nur noch ueber `SourceSystemDefinitions`
+- `ConfigTransferService` hat keinen aktiven Legacy-Credential-Pfad mehr
+- die fruehere Temp-Datei `standorte_numbered.tmp` wurde entfernt
+
+Wichtig:
+
+- bestehende DB-Spalten koennen physisch noch vorhanden sein, sind aber kein aktiver Codepfad mehr
+- fuehrende Wahrheit fuer zentrale Zugangsdaten ist jetzt ausschliesslich `SourceSystemDefinition`
+
+### Schema-Bereinigung
+
+Danach wurde auch die SQLite-Schemabereinigung nachgezogen.
+
+Aktueller Stand:
+
+- `DatabaseInitializationService` erkennt alte Credential-Spalten in `ExportSettings`
+- wenn diese Legacy-Spalten noch existieren, wird `ExportSettings` beim Start auf das neue Schema rekonstruiert
+- erhalten bleiben nur die noch gueltigen Felder:
+  - `DateFilter`
+  - `TimerHour`
+  - `TimerMinute`
+  - `TimerEnabled`
+  - `DebugLoggingEnabled`
+  - `LocalSiteExportFolder`
+  - `LocalConsolidatedExportFolder`
+
+Damit gilt jetzt:
+
+- alte zentrale SAP/BI1/SAGE-Credentials sind nicht nur logisch entfernt
+- sie werden bei bestehender DB auch aktiv aus dem `ExportSettings`-Schema entfernt
+
+### Letzte Bereinigung HANA-Credentials
+
+Danach wurde auch die letzte doppelte Credential-Stelle in der HANA-Verwaltung entfernt.
+
+Aktueller Stand:
+
+- zentrale HANA-Konfiguration speichert nur noch technische Verbindungsdaten
+  - `Host`
+  - `Port`
+  - `DatabaseName`
+  - `UseSsl`
+  - `ValidateCertificate`
+  - `AdditionalParams`
+- Username/Password werden nicht mehr in der zentralen HANA-UI gepflegt
+- HANA-Verbindungstests in `Standorte.razor` verwenden jetzt die zentralen Credentials aus `SourceSystemDefinition`
+- `SiteExportService` faellt bei HANA nicht mehr auf in `HanaServer` gespeicherte Credentials zurueck
+- `ConfigTransferService` exportiert/importiert fuer `HanaServer` keine Username-/Password-Werte mehr
+- `DatabaseInitializationService` bereinigt bei bestehender DB auch das `HanaServers`-Schema und entfernt die Altspalten `Username` / `Password`
+
+Die fachliche Reihenfolge ist jetzt eindeutig:
+
+1. zentrale Credentials aus `SourceSystemDefinition`
+2. optionale Override-Credentials am `Site`
+3. technische HANA-Verbindung aus der zentralen HANA-Konfiguration
+
+### EF-/SQLite-Fix
+
+Beim ersten Lauf nach der Schema-Bereinigung trat noch ein Mapping-Fehler auf:
+
+- `SQLite Error 1: 'no such column: h.Password'`
+
+Ursache:
+
+- `HanaServers`-Schema war bereits ohne `Username` / `Password`
+- das EF-Modell `HanaServer` hat diese Properties aber noch als normale Spalten behandelt
+
+Fix:
+
+- `HanaServer.Username` und `HanaServer.Password` sind jetzt `[NotMapped]`
+- damit bleiben sie fuer Laufzeit-Verbindungsaufbau und Tests nutzbar
+- EF erwartet sie aber nicht mehr als Datenbankspalten
+
+## Nachtrag Zentrale SAP-Steuerung 2026-04-17
+
+Der verbleibende Architekturbruch bei SAP wurde ebenfalls bereinigt.
+
+### Neuer Stand
+
+- `SourceSystemDefinition` enthaelt jetzt auch `CentralServiceUrl`
+- zentrale SAP-Service-URL wird damit am Quellsystem gepflegt, nicht mehr primaer am Standort
+- `Standorte.razor` behandelt `SapServiceUrl` jetzt als Override
+- wenn kein Override gesetzt ist, zieht SAP die URL zentral aus dem Quellsystem
+
+### UI
+
+- `Settings.razor` hat fuer Quellsysteme jetzt eine Dialogbearbeitung statt nur Inline-Tabellenfelder
+- dadurch ist das Quellsystem sauber editierbar
+- fuer `SAP_GATEWAY` wird dort die zentrale SAP-Service-URL gepflegt
+- `Standorte.razor` zeigt bei SAP jetzt:
+  - zentrale SAP Service URL
+  - optionales `SAP Service URL Override`
+
+### Laufzeitlogik
+
+- `SiteExportService` verwendet bei SAP die effektive URL aus
+  - Standort-Override
+  - sonst `SourceSystemDefinition.CentralServiceUrl`
+- SAP-Verbindungstest in `Settings.razor` testet die zentrale URL direkt aus dem Quellsystem
+- Dashboard zeigt fuer SAP jetzt ebenfalls die effektive zentrale bzw. ueberschriebene URL
+
+### Verifikation
+
+Nach der Umstellung geprueft:
+
+```text
+dotnet build .\TrafagSalesExporter.csproj -v minimal
+dotnet test .\TrafagSalesExporter.Tests\TrafagSalesExporter.Tests.csproj --verbosity minimal
+```
+
+Ergebnis:
+
+- Build erfolgreich
+- Tests erfolgreich
+- `31/31` Tests gruen
+
+## Nachtrag 2026-04-16
+
+Seit dem letzten Handoff wurden weitere Funktionen umgesetzt, die unten im alten Stand noch nicht voll enthalten sind.
+
+## Zielbild
+
+Die App wurde von einem reinen BI1/HANA-Exporter zu einer kombinierten Plattform erweitert:
+
+- `BI1` und `SAGE` bleiben auf direktem HANA-Zugriff
+- `SAP` laeuft separat ueber SAP Gateway / OData
+- SAP-Quellen koennen gelesen, gejoint und auf das zentrale `SalesRecord`-Schema gemappt werden
+- Standort-Exporte werden lokal als Excel geschrieben
+- zusaetzlich werden Datensaetze in eine zentrale SQLite-Tabelle geschrieben
+- ein konsolidierter Export liest aus dieser zentralen Tabelle
+
+## Wichtigste umgesetzte Funktionen
+
+### 1. Zentrale Credentials pro Quellsystem
+
+Es gibt zentrale Zugangsdaten in `ExportSettings` fuer:
+
+- `SAP`
+- `BI1`
+- `SAGE`
+
+Zusaetzlich gibt es pro Standort optionale Overrides:
+
+- `UsernameOverride`
+- `PasswordOverride`
+
+Aufloesungsreihenfolge:
+
+1. Standort-Override
+2. zentrale Credentials des Quellsystems
+3. bei HANA zusaetzlich Fallback auf alten `HanaServer.Username/Password`
+
+### 2. SAP von BI1/HANA getrennt
+
+`SAP` nutzt nicht mehr den HANA-Pfad, sondern eine eigene Gateway/OData-Strecke.
+
+Pro SAP-Standort gibt es:
+
+- `SapServiceUrl`
+- `SapEntitySet`
+- `SapEntitySetsCache`
+- `SapEntitySetsRefreshedAtUtc`
+
+Refresh der SAP-Quellen erfolgt nur auf Knopfdruck.
+
+Beispiel Service URL:
+
+```text
+http://travt762.sap.trafag.com:8000/sap/opu/odata/sap/ZPOWERBI_EINKAUF_SRV/
+```
+
+Wichtig:
+
+- Service URL immer nur bis zum Service
+- Entity Set separat auswaehlen
+
+### 3. SAP-Quellen, Joins und Feldmappings
+
+Fuer SAP gibt es mehrere neue Modelle:
+
+- `SapSourceDefinition`
+- `SapJoinDefinition`
+- `SapFieldMapping`
+
+Unterstuetzt wird:
+
+- mehrere SAP-Quellen pro Standort
+- Alias pro Quelle
+- Primaerquelle
+- Join-Definitionen
+- Mapping von `Alias.Feldname` auf zentrales Schema
+
+UI-Erweiterungen:
+
+- `Quellen refreshen`
+- `Felder aus Quellen laden`
+- Join-Key-Auswahl aus Metadaten
+- `Auto-Match` fuer gleiche Feldnamen zwischen Primaerquelle und anderen Quellen
+
+### 4. Zentrale Datenspeicherung
+
+Neue Tabelle:
+
+- `CentralSalesRecords`
+
+Verwendung:
+
+- pro Standort werden alte zentrale Saetze dieses Standorts ersetzt
+- konsolidierte Excel liest aus `CentralSalesRecords`
+
+Wichtig:
+
+- zentrale Excel wird nicht appendet
+- sie wird aus dem aktuellen Zustand der zentralen Tabelle neu erstellt
+
+### 5. Exportpfade
+
+Neue Konfigurationsmoeglichkeiten:
+
+Zentral in `Settings`:
+
+- `LocalSiteExportFolder`
+- `LocalConsolidatedExportFolder`
+
+Pro Standort:
+
+- `LocalExportFolderOverride`
+
+Fallback wenn leer:
+
+```text
+./output
+```
+
+relativ zum App-Verzeichnis.
+
+### 6. SharePoint
+
+SharePoint-Upload ist optional.
+
+Wenn keine vollstaendige SharePoint-Konfiguration vorhanden ist:
+
+- Excel wird trotzdem lokal erzeugt
+- kein Upload nach SharePoint
+
+Benoetigte SharePoint-Werte:
+
+- `Tenant ID`
+- `Client ID`
+- `Client Secret`
+
+Das sind Entra App Registration Werte, nicht normale Benutzer-Credentials.
+
+### 7. Config Import/Export
+
+Es gibt JSON-Import/Export der Konfiguration mit Checkbox:
+
+- mit Secrets
+- ohne Secrets
+
+Enthalten sind u. a.:
+
+- SharePoint Config
+- ExportSettings
+- HanaServers
+- Sites
+- Transformation Rules
+- SAP-Quellen
+- SAP-Joins
+- SAP-Mappings
+
+### 8. Logging und Live-Status
+
+Neue technische Logs ueber `AppEventLogs`.
+
+Sichtbar:
+
+- auf `/logs`
+- im Dashboard als `Live-Status`
+
+Geloggt werden u. a.:
+
+- HANA-Query Start
+- SAP Refresh
+- SAP Reads
+- Transformationen
+- Excel-Erstellung
+- zentrale Tabellenspeicherung
+- Export erfolgreich / fehlgeschlagen
+
+### 9. Excel oeffnen
+
+Im Dashboard gibt es neben `Export` den Button:
+
+- `Excel oeffnen`
+
+Dieser nutzt `ExportLogs.FilePath`.
+
+Voraussetzungen:
+
+- letzter Export erfolgreich
+- `FilePath` gespeichert
+- Datei existiert lokal
+
+### 10. Management Cockpit
+
+Es gibt einen neuen Menuepunkt:
+
+- `Management Cockpit`
+
+Funktion:
+
+- Auswahl vorhandener Excel-Dateien
+- Analyse einer exportierten Standort-Datei
+- Kennzahlen fuer Geschaeftsinhaber / Management
+
+Aktuell enthalten:
+
+- Umsatz
+- geschaetzte Kosten
+- geschaetzte Marge
+- Rechnungsanzahl
+- Kundenanzahl
+- Top Kunden
+- Top Produktgruppen
+- Top Sales Owner
+- Datenqualitaetshinweise
+- automatische Management-Aussagen
+
+### 11. Manueller Excel-Import pro Standort
+
+Es gibt jetzt einen vierten `SourceSystem`-Typ:
+
+- `MANUAL_EXCEL`
+
+Gedanke:
+
+- Standort ohne Netz-/Systemanbindung liefert nur Excel
+- Datei wird im Standort hochgeladen
+- Export liest diese Datei statt SAP/HANA
+- Daten werden in `CentralSalesRecords` fuer diesen Standort ersetzt
+- der zentrale Export liest weiter nur aus `CentralSalesRecords`
+
+Neue Site-Felder:
+
+- `ManualImportFilePath`
+- `ManualImportLastUploadedAtUtc`
+
+Wichtig:
+
+- das ist kein Excel-zu-Excel-Merge
+- die App importiert ins zentrale Schema und erzeugt danach die zentrale Datei neu
+
+### 12. Dashboard erweitert
+
+Im Dashboard gibt es jetzt zusaetzlich:
+
+- separaten Bereich `Zentrale Datei`
+- `Excel oeffnen` fuer die neueste zentrale Datei `Sales_All_*.xlsx`
+- Button `Alle exportieren`
+- Button `Zentrale Datei neu erzeugen`
+
+Bedeutung:
+
+- `Alle exportieren` liest alle Quellen neu und erzeugt danach die zentrale Datei
+- `Zentrale Datei neu erzeugen` schreibt nur aus `CentralSalesRecords` eine neue zentrale Excel
+
+### 13. Management Cockpit Roh-Auswertung aus Zentraldaten
+
+Zusaetzlich zur dateibasierten Cockpit-Analyse gibt es jetzt eine Roh-Auswertung direkt aus `CentralSalesRecords`.
+
+Aktuell umgesetzt:
+
+- Auswahl Jahr
+- optional Auswahl Monat
+- Jahresumsatz
+- Monatsumsatz
+- Tagesumsatz im gewaehlten Monat
+- Umsatz nach Quelle
+- Umsatz nach Land
+- Periodenabdeckung / Zeilen / Rechnungen / Standorte / Laender / Waehrungen
+
+Bewusst noch nicht enthalten:
+
+- kein Intercompany-Filter
+- keine CHF-Umrechnung
+- kein Budgetvergleich
+- keine Spartenlogik
+- keine Gruppenlogik
+- keine Margenlogik
+
+### 14. Transformationssystem erweitert
+
+Das Transformationssystem kann jetzt zwei Ebenen:
+
+- `Value` fuer einfache feldweise Regeln aus der GUI
+- `Record` fuer komplexere C#-Strategien per Strategy Pattern
+
+Umgesetzt:
+
+- neues Feld `RuleScope` auf `FieldTransformationRule`
+- dynamischer Strategiekatalog
+- GUI liest verfuegbare Typen aus dem Katalog
+- erste `Record`-Strategie: `FirstNonEmpty`
+
+Beispiel:
+
+- `TargetField = CustomerName`
+- `TransformationType = FirstNonEmpty`
+- `Argument = CustomerName|SupplierName|Name`
+
+### 15. Schema-Lookup fuer HANA-Standorte
+
+Im Standortdialog fuer HANA-basierte Standorte gibt es jetzt:
+
+- Button `Schemas laden`
+- Lookup mit gueltigen Schemas aus HANA
+
+Die Liste wird nicht blind aus allen Schemas gelesen, sondern auf typische B1-Schemas eingeschraenkt, in denen z. B. Tabellen wie
+
+- `OINV`
+- `INV1`
+- `ORIN`
+- `RIN1`
+- `OCRD`
+- `OITM`
+
+vorhanden sind.
+
+Wichtig:
+
+- manuelle Eingabe bleibt moeglich
+- fuer `BI1` und `SAGE` werden beim Lookup die effektiven Credentials inkl. zentraler Zugangsdaten / Overrides verwendet
+- das reduziert Fehler wie `invalid schema name`
+
+### 16. Testabdeckung ausgebaut
+
+Es gibt jetzt ein separates Testprojekt:
+
+- `TrafagSalesExporter.Tests`
+
+Automatisiert getestet werden aktuell:
+
+- Transformationsstrategien
+- `RecordTransformationService`
+- `TransformationCatalog`
+- `ManualExcelImportService`
+- `ManagementCockpitService`
+- `ConfigTransferService`
+
+Wichtiger bereits gefundener Bug:
+
+- deutsches Dezimalformat wie `1,50` wurde im manuellen Excel-Import falsch interpretiert
+- Parsing wurde korrigiert
+

+
+## Datenbank / Migrationen
+
+Viele Aenderungen laufen ueber `DatabaseInitializationService`.
+
+Wichtige neue oder erweiterte Tabellen/Felder:
+
+- `Sites`
+  - `UsernameOverride`
+  - `PasswordOverride`
+  - `SapServiceUrl`
+  - `SapEntitySet`
+  - `SapEntitySetsCache`
+  - `SapEntitySetsRefreshedAtUtc`
+  - `LocalExportFolderOverride`
+  - `ManualImportFilePath`
+  - `ManualImportLastUploadedAtUtc`
+- `ExportSettings`
+  - zentrale SAP/BI1/SAGE Credentials
+  - `LocalSiteExportFolder`
+  - `LocalConsolidatedExportFolder`
+  - `DebugLoggingEnabled`
+- `FieldTransformationRules`
+  - `RuleScope`
+- `ExportLogs`
+  - `FilePath`
+- neue Tabellen:
+  - `AppEventLogs`
+  - `CentralSalesRecords`
+  - SAP-Konfigtabellen
+
+## Letztes Hauptproblem und Loesung
+
+### Export hing nach zentraler Speicherung
+
+Der Export blieb zuletzt nach
+
+- `Zentrale Tabelle: 20106 Datensaetze gespeichert.`
+
+haengen.
+
+Die eigentliche Ursache war am Ende nicht mehr der Batch-Insert selbst, sondern ein kaputter SQLite-Schemazustand:
+
+- mindestens eine Tabelle referenzierte per FK noch `main.Sites_old`
+- dadurch scheiterte `SaveChangesAsync()` spaeter beim Schreiben in `AppEventLogs` oder `ExportLogs`
+- die alte Tabelle `Sites_old` existierte nicht mehr
+
+Beobachteter Fehler:
+
+- `SQLite Error 1: 'no such table: main.Sites_old'`
+
+## Umgesetzte Korrekturen
+
+- `Components/Pages/Dashboard.razor`
+  - Live-Status pollt waehrend laufendem Export nicht mehr permanent `AppEventLogs`
+  - stattdessen Anzeige ueber den In-Memory-Status aus `ExportOrchestrationService`
+- `Program.cs`
+  - SQLite `Default Timeout` von `10` auf `60` erhoeht
+- `Services/CentralSalesRecordService.cs`
+  - nach abgeschlossenem Batch-Insert wird explizit `Zentrale Tabelle aktualisiert` gesetzt
+- `Services/DatabaseInitializationService.cs`
+  - automatische Reparaturlogik fuer Tabellen, deren `CREATE TABLE`-SQL noch `Sites_old` referenziert
+  - betroffene Tabellen werden beim Start neu aufgebaut und Daten rueberkopiert
+
+Danach wurde der Export erfolgreich getestet und geht jetzt wieder durch.
+
+## Was bei einer naechsten Stoerung zuerst zu pruefen ist
+
+1. Tritt beim App-Start die Schema-Reparatur sauber durch?
+2. Gibt es noch weitere Tabellen mit FK-Referenz auf `Sites_old`?
+3. Erst danach wieder Insert-/Commit-Batches der zentralen Speicherung untersuchen
+
+## Build-Status
+
+Letzter Build:
+
+```text
+dotnet build TrafagSalesExporter.sln
+```
+
+Ergebnis:
+
+- erfolgreich
+- bekannte Warnungen bleiben:
+  - SAP HANA Architekturwarnung `MSB3270`
+  - MudBlazor Analyzer `Dense`
+
+## Nachtrag 2026-04-17 UI-Klarstellung HANA vs. SAP
+
+- `Components/Pages/Standorte.razor`
+  - Bereich oben heisst jetzt bewusst `Zentrale HANA-Technik`
+  - Hinweistext stellt klar: dort erscheinen nur Quellsysteme mit Anschlussart `HANA`
+  - `SAP` wird zentral unter `Settings -> Quellsysteme` gepflegt und gehoert nicht in diese Box
+  - der irrefuehrende Button `Server hinzufuegen` wurde entfernt
+  - neue HANA-Zeilen entstehen aus den Quellsystem-Stammdaten, nicht mehr aus einer zweiten UI-Erfassung
+  - Dialogtitel fuer HANA wurde auf reine Bearbeitung der zentralen Technik reduziert
+
+Fachliche Regel jetzt:
+
+- `Quellsysteme` verwalten die zentralen Systeme und deren Anschlussart
+- `Standorte` zeigen fuer HANA nur noch die technische Zentralverbindung
+- `SAP` wird nicht mehr implizit in der HANA-Box erwartet
+
+## Nachtrag 2026-04-17 Pruefung Config-Import/Export
+
+Der aktuelle Config-Transfer wurde nach den Umbauten nochmals geprueft.
+
+Status:
+
+- Das aktuelle Import-/Exportformat passt zum neuen Modell.
+- `SourceSystemDefinitions` werden mit `ConnectionKind`, `CentralServiceUrl`, `CentralUsername`, `CentralPassword` importiert/exportiert.
+- `HanaServers` enthalten nur noch technische HANA-Verbindungsdaten und keine Credentials mehr.
+- Standort-Overrides fuer Username/Password sowie SAP Service URL gehen weiterhin mit.
+- Die vorhandenen `ConfigTransferServiceTests` laufen grün.
+
+Weiterhin offene Architekturpunkte:
+
+- `ConfigTransferService.ImportJsonAsync` ist weiterhin destruktiv und nicht atomar.
+  - Erst werden bestehende Daten geloescht, danach wird in mehreren Schritten neu aufgebaut.
+  - Wenn der Import in der Mitte scheitert, bleibt ein teilweiser Zustand zurueck.
+- Altformat-Risiko bei `ConnectionKind`:
+  - Wenn ein aelteres JSON bereits `SourceSystemDefinitions` enthaelt, aber noch ohne `ConnectionKind`, faellt der DTO-Default auf `HANA`.
+  - Dadurch koennte ein altes `SAP` beim Import falsch als `HANA` landen.
+
+Fazit:
+
+- Fuer Exporte aus dem aktuellen Stand ist der Config-Transfer konsistent.
+- Fuer aeltere JSON-Staende braucht der Import noch eine explizite Migrations-/Fallback-Logik.

+# Handoff: DataSourceAdapter-Refactoring (2026-04-17)
+
+**Branch:** `claude/review-trafag-tool-JONMq`
+**Commit:** `82ac7df` ("DataSourceAdapter-Pattern + SiteExportService schlanker + Page-Services Scoped")
+**Basis:** `main` @ `2a56ba5` (umfangreiches refactoring)
+
+## Kontext fuer den naechsten LLM
+
+Vorheriges Review hatte drei Architektur-Punkte beanstandet:
+1. `SiteExportService` war zu gross (338 Zeilen, if/else auf ConnectionKind)
+2. Fehlende Adapter-Abstraktion fuer Datenquellen (HANA / SAP_GATEWAY / MANUAL_EXCEL)
+3. Alle Services Singleton, auch UI-nahe Page-Services
+
+Dieses Refactoring adressiert alle drei Punkte. **Nicht** im Scope (absichtlich offen gelassen):
+- SQL-Injection-Risiko in `HanaQueryService:191,204`
+- `.GetAwaiter().GetResult()` Blocking in `HanaQueryService`
+- Secret-Store-Integration
+- Retry/Polly
+
+## Was konkret geaendert wurde
+
+### Neu: `Services/DataSources/`
+| Datei | Zweck |
+|---|---|
+| `IDataSourceAdapter.cs` | Interface mit `ConnectionKind` + `FetchAsync(context)` |
+| `DataSourceFetchContext.cs` | Input: Site, SourceDefinition, Settings, SharePointConfig, UpdateStatus |
+| `DataSourceFetchResult.cs` | Output: Records + optionaler `ReferenceFilePath` (Manual Excel liefert Quell-Datei als Referenz) |
+| `IDataSourceAdapterResolver.cs` + `DataSourceAdapterResolver.cs` | Dictionary-Lookup nach ConnectionKind |
+| `HanaDataSourceAdapter.cs` | Baut `HanaServer` aus zentraler Config + Site-Overrides, ruft `IHanaQueryService.GetSalesRecords` |
+| `SapGatewayDataSourceAdapter.cs` | Laedt SapSources/Joins/Mappings, ruft `ISapCompositionService.BuildSalesRecordsAsync` |
+| `ManualExcelDataSourceAdapter.cs` | Lokale Datei oder SharePoint-Download, ruft `IManualExcelImportService.ReadSalesRecordsAsync` |
+| `DataSourceCredentials.cs` | Interner Helper (FirstNonEmpty, Resolve, ResolveSapServiceUrl) |
+
+### Geaendert: `Services/SiteExportService.cs`
+338 -> 187 Zeilen. Jetzt reine Pipeline:
+```
+1. NormalizeSourceSystem
+2. LoadExportConfigAsync (settings, spConfig, sourceDefinition, rules) - 1x DbContext
+3. Resolve adapter per ConnectionKind
+4. adapter.FetchAsync -> records (+ optional ReferenceFilePath)
+5. Transform (_transformationService.Apply)
+6. Excel erzeugen (falls Adapter keine Referenzdatei liefert)
+7. CentralSalesRecordService.ReplaceForSiteAsync
+8. UploadToSharePointIfConfiguredAsync
+```
+Entferntes Dead-Injection: `ISapGatewayService` (wurde konstruiert aber nie benutzt).
+
+### Geaendert: `Program.cs`
+- Adapter registriert (3x `AddSingleton<IDataSourceAdapter, ...>` + Resolver)
+- **Page-Services auf Scoped** (`ISettingsPageService`, `IStandortePageService`, `IStandorteSapEditorService`, `IManagementCockpitPageService`, `IDashboardPageService`, `ILogsPageService`, `ITransformationsPageService`) — pro Blazor-Circuit
+- `ExportOrchestrationService` bleibt bewusst Singleton (geteilter Export-Status ueber Circuits via `OnExportStatusChanged`)
+- Stateless Connector-/Infra-Services bleiben Singleton
+
+## Was der naechste LLM pruefen / testen soll
+
+### 1. Build (ICH KONNTE NICHT BAUEN — kein dotnet SDK in der Sandbox)
+```bash
+cd TrafagSalesExporter
+dotnet restore
+dotnet build
+```
+Falls Fehler: hohe Wahrscheinlichkeit, dass ich ein `using` vergessen oder einen Interface-Namen vertippt habe. Kandidaten fuer Tippfehler: `DataSourceCredentials.FirstNonEmpty` in `SiteExportService.cs:181`, Adapter-Constructoren in `Services/DataSources/*.cs`.
+
+### 2. Tests laufen lassen
+```bash
+cd TrafagSalesExporter
+dotnet test
+```
+Bestehende Tests in `TrafagSalesExporter.Tests/` referenzieren **keinen** der refactorierten Services direkt (siehe grep: `SiteExportService|IDataSource` liefert keine Treffer in Tests). Sollten also gruen bleiben.
+
+### 3. Manueller Smoke-Test der drei Quellsysteme
+In der Blazor-UI (Standorte-Seite, Export-Button):
+- **HANA-Standort**: Export starten — muss wie vorher Records aus HANA ziehen, Excel erzeugen, zentrale Tabelle aktualisieren, optional nach SharePoint uploaden.
+- **SAP_GATEWAY-Standort**: Export starten — muss SAP-Quellen/Joins/Mappings laden, Records ueber `SapCompositionService` bauen.
+- **MANUAL_EXCEL-Standort** (lokaler Pfad): Referenz-Excel wird gelesen, **keine** neue Excel-Datei erzeugt (Referenzdatei bleibt).
+- **MANUAL_EXCEL-Standort** (SharePoint-Pfad, `/Shared Documents/...`): temporaerer Download, lesen, Temp-Datei wird im `finally` wieder geloescht.
+
+**Verhaltens-Aequivalenz** zur vorherigen Implementierung ist das Pruefkriterium — keine neue Funktionalitaet, nur Struktur.
+
+### 4. Captive-Dependency-Check
+Scoped -> Singleton wuerde DI-Fehler werfen. Ich habe per grep verifiziert, dass kein Singleton eine `I*PageService` konsumiert. Wer das nochmal manuell pruefen moechte:
+```bash
+grep -rn "PageService" TrafagSalesExporter/Services/ | grep -v "PageService.cs"
+```
+Sollte nur Registrierungen in Program.cs und UI-Komponenten zeigen.
+
+### 5. Erweiterbarkeit testen
+Um ein viertes Quellsystem hinzuzufuegen, reicht jetzt:
+1. Konstante in `Models/SourceSystemDefinition.cs::SourceSystemConnectionKinds`
+2. Neuer `IDataSourceAdapter` in `Services/DataSources/`
+3. `builder.Services.AddSingleton<IDataSourceAdapter, NeuerAdapter>();` in `Program.cs`
+
+Kein Eingriff in `SiteExportService` noetig.
+
+## Offene Themen fuer Follow-up-PRs
+
+1. **SQL-Injection (kritisch)** — `HanaQueryService.cs:191,204`: `schema`, `tsc`, `dateFilter` via String-Interpolation. Auf `HanaCommand`-Parameter umstellen (Beispiel: `GetAvailableSchemas()` nutzt das bereits korrekt).
+2. **Blocking async** — `HanaQueryService` hat 8x `.GetAwaiter().GetResult()`. In Blazor Server Deadlock-Risiko — auf echtes `async/await` migrieren.
+3. **Tests fuer Adapter** — Unit-Tests fuer die drei neuen Adapter mit Fakes der Connector-Services waeren sinnvoll. `DataSourceAdapterResolver`-Test (Dictionary-Lookup, Fehler bei unbekanntem Kind) einfach zu schreiben.
+4. **Retry-Layer** — HTTP-Requests zu SharePoint/SAP Gateway ohne Polly. Bei Netzflackern bricht Export ab.

+# TrafagSalesExporter LLM System Guide
+
+Stand: 2026-04-17
+
+Diese Datei ist fuer andere LLMs gedacht, die das Projekt schnell verstehen und daraus Architekturtexte, Visualisierungen, Ablaufdiagramme oder UI-/Datenflussgrafiken erzeugen sollen.
+
+## Zweck des Systems
+
+`TrafagSalesExporter` ist eine Blazor Server App auf `.NET 8`, die Verkaufsdaten aus mehreren Quellsystemen in ein gemeinsames Zielschema ueberfuehrt.
+
+Quellsysteme:
+
+- `HANA`-basierte Systeme wie `BI1` und `SAGE`
+- `SAP_GATEWAY` ueber OData
+- `MANUAL_EXCEL` aus hochgeladenen oder referenzierten Excel-Dateien
+
+Zielbild:
+
+- jede Quelle wird in `SalesRecord` normalisiert
+- Standortdaten koennen lokal als Excel exportiert werden
+- alle Datensaetze werden in `CentralSalesRecords` gespeichert
+- eine zentrale konsolidierte Datei wird aus dem zentralen Datenbestand erzeugt
+- ein `Management Cockpit` analysiert sowohl exportierte Dateien als auch zentrale Rohdaten
+
+## Technologie-Stack
+
+- UI: Blazor Server + MudBlazor
+- Datenbank: SQLite (`trafag_exporter.db`)
+- Excel lesen/schreiben: ClosedXML
+- SAP HANA Zugriff: `Sap.Data.Hana.Core.v2.1.dll`
+- SAP Gateway / OData: eigener Service ueber HTTP
+- SharePoint Upload/Download: Microsoft Graph + Azure Identity
+- Tests: xUnit
+
+## Einstiegspunkte

+- [Components/Layout/NavMenu.razor](C:/Users/koi/source/repos/Ai/TrafagSalesExporter/Components/Layout/NavMenu.razor)
+
+`Program.cs` registriert fast die komplette Architektur ueber DI und fuehrt beim Start `DatabaseInitializationService.InitializeAsync()` aus.

+
+## Der wichtigste technische Ablauf
+
+### 1. Standort-Export
+
+Pfad:
+
+`Dashboard/Standorte -> ExportOrchestrationService -> SiteExportService`
+
+`SiteExportService` unterscheidet drei Modi:
+
+1. `SAP_GATEWAY`
+   - SAP-Quellen lesen
+   - SAP-Joins anwenden
+   - SAP-Feldmappings auf `SalesRecord`
+   - Transformationen anwenden
+   - Standort-Excel erzeugen
+   - `CentralSalesRecords` ersetzen
+   - optional SharePoint-Upload
+
+2. `HANA`
+   - effektive zentrale HANA-Konfiguration laden
+   - optionale Standort-Credential-Overrides anwenden
+   - SQL in HANA ausfuehren
+   - `SalesRecord` erzeugen
+   - Transformationen anwenden
+   - Standort-Excel erzeugen
+   - `CentralSalesRecords` ersetzen
+   - optional SharePoint-Upload
+
+3. `MANUAL_EXCEL`
+   - `ManualImportFilePath` auswerten
+   - wenn lokal/UNC vorhanden: lokal lesen
+   - wenn SharePoint-Referenz: via Graph temp herunterladen
+   - Excel in `SalesRecord` lesen
+   - Transformationen anwenden
+   - keine neue Standortdatei erzeugen, bestehende Excel dient als Eingabe
+   - `CentralSalesRecords` ersetzen
+
+### 2. Konsolidierter Export
+
+Pfad:
+
+`Dashboard -> ExportOrchestrationService -> ConsolidatedExportService`
+
+Semantik aktuell:
+
+- die zentrale Datei basiert fachlich auf `CentralSalesRecords`
+- `ExportAllAsync()` sammelt zwar auch `consolidatedRecords`, aber die zentrale Exportsemantik ist historisch noch nicht vollkommen bereinigt
+
+### 3. Management Cockpit
+
+Zwei Betriebsarten:
+
+1. Dateibasiert
+   - vorhandene `.xlsx` waehlen
+   - Datei mit ClosedXML lesen
+   - Kennzahlen, Top-Listen, Datenqualitaet, Findings erzeugen
+
+2. Zentraldatenbasiert
+   - direkt aus `CentralSalesRecords`
+   - Jahr/Monat Filter
+   - Rohsicht ohne Intercompany-, CHF-, Budget- oder Spartelogik
+
+## Quellsystemlogik
+
+### SourceSystemDefinition
+
+`SourceSystemDefinition` ist die fuehrende Wahrheit fuer:
+
+- `Code`
+- `DisplayName`
+- `ConnectionKind`
+- `IsActive`
+- `CentralUsername`
+- `CentralPassword`
+- `CentralServiceUrl` fuer SAP
+
+Anschlussarten:
+
+- `HANA`
+- `SAP_GATEWAY`
+- `MANUAL_EXCEL`
+
+### HANA
+
+Fachliche Logik:
+
+- zentrale technische HANA-Konfiguration pro Quellsystem
+- keine separaten Vollverbindungen pro Standort
+- Standort speichert nur Fachdaten plus optionale Username-/Password-Overrides
+
+Schema-Lookup:
+
+- in `Standorte` gibt es jetzt `Schemas laden`
+- Lookup fragt `sys.tables` in HANA ab
+- eingeschraenkt auf typische B1-Schemas mit Tabellen wie `OINV`, `INV1`, `ORIN`, `RIN1`, `OCRD`, `OITM`
+
+### SAP
+
+Fachliche Logik:
+
+- zentrale SAP Service URL in `SourceSystemDefinition.CentralServiceUrl`
+- Standort kann `SapServiceUrl` als Override pflegen
+- pro Standort gibt es SAP-Quellen, Joins und Feldmappings
+
+### Manual Excel
+
+Fachliche Logik:
+
+- `Site.ManualImportFilePath` kann sein:
+  - lokaler Windows-Pfad
+  - UNC-Pfad
+  - SharePoint-URL
+  - SharePoint-Pfad unterhalb der konfigurierten Site
+- Standortdaten werden aus der Excel eingelesen und in `CentralSalesRecords` uebernommen
+- SharePoint dient hier als Eingangsquelle, nicht nur als Exportziel
+
+## Transformationen
+
+Das System unterscheidet:
+
+- `Value`-Transformationen
+- `Record`-Transformationen
+
+Beispiele:
+
+- `Copy`
+- `Uppercase`
+- `Lowercase`
+- `Prefix`
+- `Suffix`
+- `Replace`
+- `Constant`
+- `NormalizeCurrencyCode`
+- `FirstNonEmpty`
+- `ConvertCurrency`
+
+Technischer Ablauf:
+
+- Regeln liegen in `FieldTransformationRules`
+- `TransformationCatalog` meldet verfuegbare Strategien an die UI
+- `RecordTransformationService` wendet record-basierte Strategien an
+
+## Wechselkurse
+
+Vorhanden:
+
+- `CurrencyExchangeRates`
+- `ExchangeRateImportService` fuer ECB-Tageskurse
+- `NormalizeCurrencyCode`
+- `ConvertCurrency`
+
+Wichtig:
+
+- die Rohsicht im `Management Cockpit` rechnet aktuell bewusst nicht in CHF um
+- CHF ist derzeit Teil des allgemeinen Transformationssystems, nicht Default in der Cockpit-Rohsicht
+
+## SharePoint-Rolle im Gesamtsystem
+
+`SharePointConfig` enthaelt:
+
+- `SiteUrl`
+- `ExportFolder`
+- `CentralExportFolder`
+- `TenantId`
+- `ClientId`
+- `ClientSecret`
+
+Verwendung:
+
+- Upload von Standort-Exporten
+- Upload der zentralen Datei
+- Download von manuellen Excel-Dateien fuer `MANUAL_EXCEL`
+
+Wichtig:
+
+- die App arbeitet gegen dieselbe SharePoint-Site, die in `Settings` konfiguriert ist
+- fuer `MANUAL_EXCEL` muessen Referenzen auf derselben Site aufloesbar sein
+
+## Startinitialisierung / Migrationen
+
+Kritische Datei:
+
+- [Services/DatabaseInitializationService.cs](C:/Users/koi/source/repos/Ai/TrafagSalesExporter/Services/DatabaseInitializationService.cs)
+
+Aktuelle Rolle:
+
+- `EnsureCreated`
+- Schema-Ergaenzungen per `ALTER TABLE`
+- Tabellen-Rebuilds bei Legacy-Schemas
+- FK-Reparaturen
+- Stammdaten-Seeding
+- empfohlene Transformationsregeln
+
+Bekannte Architekturrealitaet:
+
+- das ist funktional hilfreich, aber kein sauberes Migrationssystem
+- die Startlogik traegt produktive Schema-Reparaturverantwortung
+- das ist einer der wichtigsten technischen Risikobloecke
+
+Bereits gehaertete Fehlerbilder:
+
+- kaputte FK-Referenzen auf `Sites_old`
+- kaputte FK-Referenzen auf `HanaServers_repair_old`
+- Legacy-Credential-Spalten in `ExportSettings`
+- Legacy-Credential-Spalten in `HanaServers`
+- verschobene Spalten im `Sites_old -> Sites`-Kopierpfad
+
+## Config Import / Export
+
+Dateien:
+
+- [Services/ConfigTransferService.cs](C:/Users/koi/source/repos/Ai/TrafagSalesExporter/Services/ConfigTransferService.cs)
+- [Models/ConfigTransferPackage.cs](C:/Users/koi/source/repos/Ai/TrafagSalesExporter/Models/ConfigTransferPackage.cs)
+
+Aktueller Stand:
+
+- JSON Export/Import fuer Konfiguration
+- Secrets optional
+- `SourceSystemDefinitions` im aktuellen Modell enthalten
+- HANA-Technik ohne HANA-Credentials
+- Standort-Overrides bleiben erhalten
+
+Wichtige Punkte:
+
+- Import laeuft jetzt transaktional
+- alte `ConnectionKind`-lose Formate bekommen Fallbacks
+- `CentralSalesRecords` werden nicht mehr blind geloescht
+- bestehende zentrale Laufzeitdaten werden fuer weiterhin vorhandene Standorte remappt
+
+## Logging
+
+Es gibt zwei Log-Ebenen:
+
+- `ExportLogs` fuer fachliche Exporthistorie
+- `AppEventLogs` fuer technische und UI-nahe Ereignisse
+
+Die `Logs`-Seite liest vor allem `AppEventLogs`.
+
+## Tests
+
+Testprojekt:
+
+- [TrafagSalesExporter.Tests](C:/Users/koi/source/repos/Ai/TrafagSalesExporter/TrafagSalesExporter.Tests)
+
+Aktuell vorhandene Schwerpunkte:
+
+- Transformationen
+- Record-Transformationen
+- TransformationCatalog
+- CurrencyExchangeRateService
+- ExchangeRateImportService
+- ManualExcelImportService
+- ManagementCockpitService
+- ConfigTransferService
+- DatabaseInitializationService
+
+Wichtig:
+
+- es gibt aktuell keine echten UI-Komponententests mit `bUnit`
+- es gibt keine Browser-E2E-Tests mit `Playwright`
+- viele Button-Aktionen sind nur indirekt ueber Services und Persistenz getestet
+
+## Bekannte offene Architekturfragen
+
+Fuer andere LLMs wichtig, damit Visualisierungen nicht zu glatt oder zu idealisiert werden:
+
+1. `DatabaseInitializationService` ist ein produktiver Reparatur-/Migrationslayer, nicht nur Bootstrap.
+2. `Settings.razor` und `Standorte.razor` enthalten weiterhin relativ viel Anwendungslogik.
+3. Die Semantik der konsolidierten Datei ist historisch teilweise doppelt angelegt.
+4. Das `Management Cockpit` ist noch kein voll generalisierter Reporting-Layer.
+5. SharePoint ist sowohl Exportziel als auch bei `MANUAL_EXCEL` mittlerweile moegliche Eingangsquelle.
+
+## Empfohlene Diagramme fuer andere LLMs
+
+### 1. Kontextdiagramm
+
+Zeige:
+
+- Benutzer
+- Blazor App
+- SQLite
+- SAP HANA
+- SAP Gateway
+- lokale Dateisystempfade
+- SharePoint
+
+### 2. Komponenten-/Service-Diagramm
+
+Gruppiere:
+
+- UI
+- Orchestrierung
+- Quelladapter
+- Transformation
+- Persistenz
+- Reporting
+
+### 3. Datenflussdiagramm pro Quelltyp
+
+Je ein separater Flow fuer:
+
+- HANA
+- SAP Gateway
+- Manual Excel lokal
+- Manual Excel SharePoint
+
+### 4. ER-Diagramm
+
+Fokussiere auf:
+
+- `SourceSystemDefinition`
+- `HanaServer`
+- `Site`
+- `SapSourceDefinition`
+- `SapJoinDefinition`
+- `SapFieldMapping`
+- `CentralSalesRecord`
+- `FieldTransformationRule`
+
+### 5. Sequenzdiagramm fuer Export
+
+Wichtige Stationen:
+
+- Dashboard
+- ExportOrchestrationService
+- SiteExportService
+- spezifischer Quellservice
+- Transformation
+- CentralSalesRecordService
+- Excel/SharePoint
+- ExportLog/AppEventLog
+
+## Prompt-Vorlage fuer ein anderes LLM
+
+Wenn ein anderes LLM daraus Visualisierungen erzeugen soll, funktioniert diese Anweisung gut:
+
+> Lies `LLM_SYSTEM_GUIDE.md` als primaeren Systemkontext. Erzeuge daraus ein Architekturdiagramm, ein Datenflussdiagramm fuer HANA/SAP/MANUAL_EXCEL, ein ER-Diagramm der wichtigsten Tabellen und ein Sequenzdiagramm fuer `ExportAsync`. Achte darauf, dass `DatabaseInitializationService` produktive Reparaturlogik enthaelt und dass `MANUAL_EXCEL` sowohl lokal als auch ueber SharePoint gelesen werden kann.
+
+## Weitere Kontextdateien
+
+Zusatzkontext fuer Verlauf und Risiken:
+
+- [HANDOFF_2026-04-15.md](C:/Users/koi/source/repos/Ai/TrafagSalesExporter/HANDOFF_2026-04-15.md)
+- [NEXT_STEPS_2026-04-15.md](C:/Users/koi/source/repos/Ai/TrafagSalesExporter/NEXT_STEPS_2026-04-15.md)
+
+Diese beiden Dateien sind wichtig, wenn ein anderes LLM nicht nur Struktur, sondern auch historische Umbauten, Risiken und Prioritaeten verstehen soll.

+
+## Nachtrag 2026-04-17
+
+Der Punkt `CHF-Umrechnung / Wechselkurse` ist nicht mehr komplett offen.
+
+Der aktuelle Ist-Stand ist:
+
+- `CurrencyExchangeRateService` ist implementiert
+- `ExchangeRateImportService` importiert ECB-Kurse
+- `NormalizeCurrencyCode` und `ConvertCurrency` sind im Transformationssystem registriert
+- fehlende Unit-Tests dafuer wurden am 2026-04-17 ergaenzt
+
+Neuer Teststand:
+
+- `dotnet test .\TrafagSalesExporter.Tests\TrafagSalesExporter.Tests.csproj --verbosity minimal`
+- erfolgreich
+- `31/31` Tests gruen
+
+Was fuer Waehrungen trotzdem noch offen bleibt:
+
+- fachlicher Einsatz der `ConvertCurrency`-Regeln in echten Standortkonfigurationen pruefen
+- UI-Flow fuer Wechselkurspflege in `Settings.razor` manuell gegenpruefen
+- ECB-Import einmal real ueber die UI bzw. App-Funktion pruefen
+- bestaetigen, fuer welche Sichten CHF die Zielwaehrung sein soll
+- Management-Cockpit-Rohsicht nur dann auf CHF umstellen, wenn fachlich gewuenscht
+
+## Architektur-Nachtrag 2026-04-17
+
+Nach einer separaten Architekturpruefung wurden die naechsten Schritte neu priorisiert.
+
+Wichtig:
+
+- neue Fachfeatures sind aktuell **nicht** der erste Engpass
+- zuerst muessen die Architektur-Risiken in Initialisierung, Config-Import und UI-Service-Schnitt bereinigt werden
+
+### Neue Top-Prioritaeten
+
+#### 1. `DatabaseInitializationService` absichern
+
+Prio sehr hoch.
+
+Gruende:
+
+- Startlogik enthaelt manuelle Schema-Migrationen
+- FK-Reparaturen laufen produktiv beim App-Start
+- dort wurde ein konkretes Risiko fuer verschobene Spaltenwerte beim `Sites_old`-Kopierpfad erkannt
+
+Vor weiterer Fachentwicklung:
+
+- Initialisierungspfad genau pruefen
+- SQL-Kopierlogik validieren
+- moeglichst Richtung versionierte Migrationen bewegen
+
+#### 2. `ConfigTransferService.ImportJsonAsync` neu denken
+
+Prio sehr hoch.
+
+Aktuelles Problem:
+
+- Import loescht sehr viel und baut danach stueckweise neu auf
+- nicht atomar
+- potenziell teilzerstoerter Zustand bei Fehlern
+- `CentralSalesRecords` werden mitimportiert/mitgeloescht, obwohl sie eher Laufzeitdaten als Konfiguration sind
+
+Ziel:
+
+- atomarer Import
+- saubere Trennung zwischen Konfiguration und Betriebsdaten
+
+#### 3. Razor-Seiten entlasten
+
+Prio hoch.
+
+Betroffen vor allem:
+
+- `Components/Pages/Settings.razor`
+- `Components/Pages/Standorte.razor`
+
+Ziel:
+
+- DB- und Fachlogik aus UI-Code in Services / Application-Layer verschieben
+- Seiten nur noch fuer Interaktion und Formularzustand
+
+#### 4. Konsolidierten Export semantisch klaeren
+
+Prio mittel.
+
+Offene Frage:
+
+- zentrale Datei aus laufendem Snapshot
+  oder
+- zentrale Datei immer aus `CentralSalesRecords`
+
+Aktuell ist die Verantwortung unscharf.
+
+#### 5. Reporting verallgemeinern
+
+Prio mittel.
+
+Erst nach den Infrastrukturthemen:
+
+- hartcodierte Jahreslogik im Cockpit entfernen
+- fachlich entscheiden, ob und wo CHF-Rohsicht gebraucht wird
+
+### Praktische Reihenfolge fuer den naechsten Wiedereinstieg
+
+Wenn nach erneutem Absturz oder Kontextverlust weitergemacht wird:
+
+1. `HANDOFF_2026-04-15.md` lesen, speziell die Architekturpruefung vom 2026-04-17
+2. `DatabaseInitializationService` als ersten Risikoblock ansehen
+3. `ConfigTransferService.ImportJsonAsync` als zweiten Risikoblock ansehen
+4. erst danach wieder an Cockpit / CHF / weitere Fachfeatures gehen
+
+## Nachtrag HANA-/Standort-Workflow 2026-04-17
+
+Der doppelte HANA-Workflow wurde inzwischen bereits bereinigt.
+
+Neuer Stand:
+
+- oben zentrale HANA-Konfiguration pro Quellsystem `BI1` / `SAGE`
+- unten im Standort keine eigene wirksame Voll-HANA-Konfiguration mehr
+- HANA-basierte Standorte ziehen ihre technische Verbindung aus der zentralen Quellsystem-Konfiguration
+- Standort bleibt fuer fachliche Daten und optionale Credential-Overrides zustaendig
+- die frueher doppelte HANA-UI im Standortdialog ist inzwischen auch sichtbar entfernt
+- der Verbindungstest in `Settings.razor` prueft und meldet jetzt die zentrale HANA-Verbindung klar
+
+### Was dazu noch praktisch geprueft werden sollte
+
+- `Standorte`-Seite im UI manuell durchklicken
+- pruefen, ob `BI1`- und `SAGE`-Standort beim Speichern sauber auf die zentrale HANA-Konfiguration zeigen
+- pruefen, ob Aenderung oben bei zentraler HANA-Konfiguration in nachfolgenden Exporten wirklich greift
+
+### Anschlussarbeiten
+
+- `ConfigTransferService` spaeter auf das neue zentrale HANA-Modell fachlich nachziehen und kritisch pruefen
+- `DatabaseInitializationService` weiter konsolidieren, damit die Zuordnung alter HANA-Daten langfristig robuster wird
+
+## Nachtrag Quellsystem-Verwaltung 2026-04-17
+
+Die bisher hart codierten Quellsystem-Listen wurden ersetzt.
+
+Neuer Stand:
+
+- `SourceSystemDefinition` ist jetzt die zentrale Stammdatenquelle fuer Quellsysteme
+- `Settings.razor` hat jetzt eine GUI zur Pflege von Quellsystemen
+- `Standorte.razor` zieht seine Quellsystem-Auswahl aus diesen Stammdaten
+- `Transformations.razor` zieht die Systemauswahl ebenfalls aus diesen Stammdaten
+- zentrale Credentials haengen jetzt am Quellsystem selbst
+- HANA-Zentralverbindungen werden nur noch fuer Quellsysteme mit Anschlussart `HANA` gezeigt
+- alte zentrale Credential-Felder in `ExportSettings` sind aus dem aktiven Codepfad entfernt
+- `ExportSettings` wird beim Start auch schematisch auf das neue Feldset bereinigt
+- HANA speichert zentral keine eigenen Credentials mehr; dort bleiben nur technische Verbindungsdaten
+- `HanaServer.Username` / `Password` sind nur noch Laufzeitfelder und nicht mehr im EF-Schema gemappt
+- SAP Service URL wird jetzt zentral im Quellsystem gepflegt; der Standort haelt nur noch ein optionales Override
+- Quellsysteme werden jetzt per Dialog bearbeitet statt nur ueber Inline-Tabellenfelder
+
+### Was dazu noch praktisch geprueft werden sollte
+
+- in `Settings` ein neues Quellsystem per GUI anlegen
+- pruefen, ob es danach in `Standorte` und `Transformations` sofort auswählbar ist
+- pruefen, ob deaktivierte Quellsysteme in neuen Standort-/Regelanlagen nicht mehr normal angeboten werden
+- pruefen, ob Aenderung der Anschlussart von `HANA` auf `SAP_GATEWAY` oder `MANUAL_EXCEL` fachlich sauber wirkt
+- pruefen, ob bestehende BI1/SAGE/SAP-Daten nach Startmigration korrekt in `SourceSystemDefinitions` stehen
+- pruefen, ob Konfiguration-Export/Import ohne die alten Credential-Felder sauber mit `SourceSystemDefinitions` arbeitet
+- pruefen, ob zentrale SAP Service URL ohne Override sauber fuer Refresh, Export und Dashboard greift
+- pruefen, ob SAP Service URL Override am Standort die zentrale URL erwartungsgemaess uebersteuert
+
+## Nachtrag 2026-04-16
+
+Seit dem letzten Stand kamen mehrere groessere Erweiterungen dazu. Die offenen Punkte unten muessen deshalb im neuen Kontext gelesen werden.
+
+## 0. Neuer Ist-Stand
+
+Zusaetzlich zum alten Stand ist jetzt vorhanden:
+
+- manueller Standort-Import ueber `MANUAL_EXCEL`
+- Dashboard mit `Alle exportieren`, `Zentrale Datei neu erzeugen` und zentralem `Excel oeffnen`
+- Roh-Auswertung im `Management Cockpit` direkt aus `CentralSalesRecords`
+- erweitertes Transformationssystem mit `Value`- und `Record`-Regeln
+- HANA-Schema-Lookup im Standortdialog
+- Testprojekt mit aktuell 18 gruenden Tests
+
+## 1. Status
+
+Der Export geht jetzt wieder durch.
+
+Die zuletzt gefundene Hauptursache war nicht mehr ein reiner SQLite-Lock beim Batch-Insert, sondern ein kaputter FK-Schemazustand in der bestehenden DB:
+
+- SQLite referenzierte in mindestens einer Tabelle noch `main.Sites_old`
+- dadurch scheiterte `SaveChangesAsync()` beim Schreiben z. B. in `AppEventLogs` oder `ExportLogs`
+- sichtbarer Effekt: Export blieb nach `Zentrale Tabelle: ... Datensaetze gespeichert.` haengen
+
+## 2. Umgesetzter Fix
+
+Umgesetzt wurde:
+
+- Dashboard-Live-Status liest waehrend laufendem Export nicht mehr staendig aus `AppEventLogs`, sondern nutzt den In-Memory-Status des `ExportOrchestrationService`
+- SQLite `Default Timeout` in `Program.cs` auf `60` erhoeht
+- `CentralSalesRecordService` setzt nach den Batches explizit `Zentrale Tabelle aktualisiert`
+- `DatabaseInitializationService` repariert beim App-Start automatisch Tabellen, deren FK-SQL noch `Sites_old` referenziert
+
+Betroffene Dateien:
+
+- `Program.cs`
+- `Components/Pages/Dashboard.razor`
+- `Services/CentralSalesRecordService.cs`
+- `Services/DatabaseInitializationService.cs`
+
+## 3. Was noch getestet werden sollte
+
+Kurz gegenpruefen:
+
+- Export eines Standorts erneut
+- `Excel oeffnen` nach erfolgreichem Export
+- `Export erfolgreich` inkl. `Pfad=...`
+- Dashboard-Live-Status setzt sich nach Abschluss sauber zurueck
+- `Alle exportieren`
+- `Zentrale Datei neu erzeugen`
+- zentrale Datei im Dashboard oeffnen
+
+## 3a. Manuellen Excel-Import pruefen
+
+Zu testen:
+
+- Standort auf `MANUAL_EXCEL` stellen
+- Excel im Standort hochladen
+- Standort exportieren
+- pruefen, ob `CentralSalesRecords` fuer diesen Standort ersetzt wurden
+- pruefen, ob der zentrale Export den Standort korrekt enthaelt
+
+Dateien:
+
+- `Components/Pages/Standorte.razor`
+- `Services/ManualExcelImportService.cs`
+- `Services/SiteExportService.cs`
+
+## 3b. HANA-Schema-Lookup pruefen
+
+Zu testen:
+
+- bei `BI1`-Standort `Schemas laden`
+- bei `SAGE`-Standort `Schemas laden`
+- wird ein plausibles B1-Schema angeboten?
+- funktioniert danach Export ohne manuelle Schema-Eingabe?
+- zeigt England / Spezialstandort jetzt schneller, wenn Schema oder Rechte nicht passen?
+
+Dateien:
+
+- `Components/Pages/Standorte.razor`
+- `Services/HanaQueryService.cs`
+
+## 4. Falls wieder ein Fehler auftritt
+
+In dieser Reihenfolge pruefen:
+
+1. Exakte Fehlermeldung aus `AppEventLogs` bzw. Console notieren
+2. Pruefen, ob die Reparaturlogik beim Start gelaufen ist
+3. Pruefen, ob noch weitere Tabellen mit veralteter FK-Referenz existieren
+4. Erst danach wieder am Batch-/Commit-Pfad der zentralen Speicherung arbeiten
+
+## 5. SAP-Funktionalitaet kurz gegenpruefen
+
+Zu testen:
+
+- `Quellen refreshen`
+- `Felder aus Quellen laden`
+- `Auto-Match`
+- SAP-Export eines Standorts
+
+Dateien:
+
+- `Components/Pages/Standorte.razor`
+- `Services/SapGatewayService.cs`
+- `Services/SapCompositionService.cs`
+
+## 6. Management Cockpit pruefen
+
+Zu testen:
+
+- vorhandene Excel-Datei auswaehlbar
+- Analyse laeuft
+- Kennzahlen plausibel
+- Roh-Auswertung aus `CentralSalesRecords` laeuft
+- Jahr/Monat-Filter funktionieren
+- Summen nach Quelle / Land plausibel
+
+Dateien:
+
+- `Components/Pages/ManagementCockpit.razor`
+- `Services/ManagementCockpitService.cs`
+
+## 6a. Fachlich bewusst noch offen
+
+Noch nicht final umsetzen ohne Rueckmeldung Fachseite:
+
+- Intercompany-Filter
+- fachliche Nutzung der CHF-Umrechnung in Cockpit / Reports
+- Budgetvergleich
+- Gruppenlogik
+- Spartenlogik
+- Margenlogik
+
+Diese Punkte sollen spaeter moeglichst dynamisch auf dem neuen Transformations-/Mapping-Ansatz aufsetzen, aber aktuell nicht hart geraten werden.
+
+## 6b. Naechste sinnvolle Testkandidaten
+
+Wenn weiter in Tests investiert wird, sind die naechsten Kandidaten:
+
+- `ExportOrchestrationService`
+- spaeter End-to-End-Tests fuer den Wechselkurs-/Transformationspfad
+- spaeter evtl. SQLite-nahe Integrationstests fuer `DatabaseInitializationService`
+
+Aktueller Teststatus:
+
+- `dotnet test .\TrafagSalesExporter.Tests\TrafagSalesExporter.Tests.csproj --verbosity minimal`
+- erfolgreich
+- `31/31` Tests gruen
+
+## 7. Referenzdatei
+
+Fuer den vollstaendigen Kontext zuerst lesen:
+
+- `HANDOFF_2026-04-15.md`
+
+## 8. Letzte bereinigte UI-Irritation
+
+Stand 2026-04-17:
+
+- In `Standorte` wurde die obere Box auf `Zentrale HANA-Technik` geklaert.
+- Dort gibt es keinen `Server hinzufuegen`-Pfad mehr.
+- Grund: zentrale HANA-Eintraege werden aus `Quellsystemen` mit Anschlussart `HANA` abgeleitet.
+- `SAP` gehoert fachlich nicht in diese Box, sondern in `Settings -> Quellsysteme`.
+
+Wichtig fuer den naechsten Wiedereinstieg:
+
+- Wenn ein Benutzer fragt `wo ist SAP?`, ist die richtige Antwort: nicht in der HANA-Box, sondern in der zentralen Quellsystem-Verwaltung.
+- Wenn ein HANA-System oben fehlt, zuerst `Settings -> Quellsysteme` pruefen und dort Anschlussart `HANA` setzen.
+
+## 9. Config-Transfer erneut geprueft
+
+Stand 2026-04-17:
+
+- Der aktuelle Config-Import/-Export passt zum neuen Datenmodell.
+- Zentral verwaltete Quellsysteme, SAP-Zentral-URL, HANA-Technik ohne HANA-Credentials und Standort-Overrides werden korrekt im Transferformat abgebildet.
+- Die vorhandenen `ConfigTransferServiceTests` bestaetigen den aktuellen Rundlauf.
+
+Fuer den naechsten Wiedereinstieg wichtig:
+
+- Das aktuelle Format ist fuer heutige Exporte konsistent.
+- `ImportJsonAsync` ist aber weiterhin nicht atomar und loescht zuerst produktive Konfiguration.
+- Zusaetzlich gibt es ein Altformat-Risiko:
+  - aeltere JSONs mit `SourceSystemDefinitions`, aber ohne `ConnectionKind`, koennen wegen DTO-Default falsch als `HANA` interpretiert werden.
+
+Naechste saubere Haertung fuer dieses Thema:
+
+- Config-Import transaktional machen
+- Legacy-Fallback fuer fehlendes `ConnectionKind` einbauen

Claude	9322e7c4ca	Handoff-Dok fuer das DataSourceAdapter-Refactoring Beschreibt was geaendert wurde, wie gebaut/getestet wird und welche Themen bewusst offen gelassen wurden (SQL-Injection, Blocking-Async).	2026-04-17 12:18:54 +00:00
Claude	82ac7df0ec	DataSourceAdapter-Pattern + SiteExportService schlanker + Page-Services Scoped - IDataSourceAdapter mit 3 Implementierungen (HANA, SAP_GATEWAY, MANUAL_EXCEL) und DataSourceAdapterResolver ersetzen das if/else auf ConnectionKind. - SiteExportService von 338 auf 187 Zeilen reduziert: Pipeline Resolve -> Fetch -> Transform -> Excel -> Central -> SharePoint. - Page-Services auf Scoped (per Blazor-Circuit); Orchestrator bleibt Singleton fuer geteilten Export-Status.	2026-04-17 12:11:35 +00:00

Claude	efcf7b180c	Add SSL, MDC database, and custom HANA connection parameters Fixes 'error while parsing protocol' HanaException by supporting SSL/TLS encryption, Multi-Tenant Database Container (MDC) database name, and arbitrary additional connection parameters. - HanaServer model: added DatabaseName, UseSsl, ValidateCertificate, AdditionalParams fields + BuildConnectionString() helper - HanaQueryService: accepts HanaServer directly, uses BuildConnectionString() for full parameter support - AppDbContext: added EnsureSchema() method that uses PRAGMA table_info + ALTER TABLE ADD COLUMN to add the new fields to existing SQLite databases without losing data (EnsureCreated does not update schema) - Program.cs: calls EnsureSchema on startup before seeding - Standorte.razor: server dialog now exposes DatabaseName, UseSsl, ValidateCertificate, AdditionalParams with helper texts; test connection uses new signature https://claude.ai/code/session_012heAXNMbbyxqYf2S2HrKLj	2026-04-13 08:52:10 +00:00
Claude	f916c26fb4	Fix SAP HANA client reference - use direct DLL reference instead of missing NuGet package Das Paket 'Sap.Data.Hana.v2' existiert nicht auf nuget.org. SAP liefert den HANA .NET Client ausschliesslich ueber das SAP HANA Client Installationspaket aus. Stattdessen wird nun Sap.Data.Hana.Core.v2.1.dll direkt aus dem Standard-Installationspfad referenziert (via HanaClientDll MSBuild-Property ueberschreibbar).
