 Stand: 2026-04-15

+## 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:
@@ -211,6 +215,132 @@ Aktuell enthalten:
 - 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
+
