+## 10. Nachtrag 2026-05-20: Finance-Regeln statt harte Laenderlogik
+
+Aktueller Stand:
+
+- Es gibt jetzt `Admin -> Finance Regeln`.
+- Die fachliche Abgrenzung fuer Finance wird dort als Regel gepflegt:
+  - Land/Scope
+  - Jahr
+  - Regeltyp
+  - Feld
+  - Vergleich
+  - Wert
+  - Notiz
+  - Sortierung/Aktiv
+- Diese Regeln wirken auf:
+  - zentrales Excel (`Finance | ...` und `Finance Summary`)
+  - Soll/Ist Vergleich
+- Sie veraendern nicht:
+  - Rohdatenimport
+  - Mapping in `Admin -> Standorte`
+  - technische Transformationen in `Admin -> Transformationen`
+
+UI-Logik fuer Keyuser:
+
+```text
+Admin -> Standorte          = Quelle und Spaltenmapping
+Admin -> Transformationen   = technische Feldnormalisierung/-berechnung
+Admin -> Finance Regeln     = CFO-/Finance-Abgrenzung
+```
+
+Wichtige Default-Regeln:
+
+- DE:
+  - Alphaplan-Jahresfile -> Finance-Jahr 2025
+  - Trafag AG ausschliessen
+  - Magnetic Sense ausschliessen
+  - GS2510095 ausschliessen
+  - GS-Gutschriften negativ
+- IT:
+  - Trafag Italia ausschliessen
+  - doppelte Blank-Supplier-Country-Zeilen deduplizieren
+
+Nach jedem Regelwechsel testen:
+
+1. passenden Standort exportieren
+2. zentrale Datei neu erzeugen
+3. im Endexcel `Finance Summary` kontrollieren
+4. `Soll/Ist Vergleich` kontrollieren
+
+Letzter DE-Pruefstand:
+
+```text
+DE 2025 im zentralen Excel: 3'652'394.46
+```
+
+## 11. Nachtrag 2026-05-20: Export Dashboard Datenbasis
+
+Im Export Dashboard steht direkt nach `Land` die Spalte `Basis`.
+
+Angezeigt wird:
+
+- `Excel-Datei` mit Tabellen-Icon
+- `CSV-Datei` mit Datei-Icon
+- `SAP Service` mit Cloud-Sync-Icon
+- `Server` mit Storage-Icon
+- `Manuelle Datei`, falls manuelle Quelle ohne erkennbaren Pfad
+
+Die Spalte kommt aus `DashboardPageService.ResolveDataBasis`.

+## Nachtrag 2026-05-20 IIS /BiDashboard PathBase
+
+Die App ist fuer Betrieb unter `/BiDashboard` vorbereitet.
+
+Relevant:
+
+- `web.config` setzt:
+
+```xml
+<environmentVariable name="ASPNETCORE_PATHBASE" value="/BiDashboard" />
+```
+
+- `Program.cs` liest `ASPNETCORE_PATHBASE` und ruft `UsePathBase(...)` auf.
+- `Components/App.razor` setzt `<base href>` dynamisch:
+  - lokal ohne PathBase: `/`
+  - Server mit PathBase: `/BiDashboard/`
+
+Damit ist die erwartete Server-URL:
+
+```text
+https://trch-webapp-bidashboard.trafagch.local/BiDashboard/
+```
+
+Wenn die App im stdout-Log startet, aber Browser weiter `404` zeigt, zuerst IIS Application/Binding pruefen:
+
+- Ist `BiDashboard` eine echte IIS Application und nicht nur ein Ordner?
+- Zeigt sie auf `C:\inetpub\wwwcust\BiDashboard` bzw. den aktuellen Publish-Ordner?
+- Stimmen Hostname, Port 443 und Zertifikat?
+
+Bekannter Login-Stand:
+
+- Wenn ein Browser-Popup `Diese Website fordert Sie auf, sich anzumelden` erscheint, ist das IIS/Windows Authentication.
+- Die App selbst hat in `appsettings.json` aktuell `Security.Enabled=false`.
+- Ein Login-Popup kommt daher von IIS, nicht von den App-internen HR-/Finance-Passwortseiten.

+## Finance-Regeln und Dashboard-Basis-Spalte 2026-05-20
+
+Geaendert:
+
+- Neuer Admin-Reiter `Finance Regeln` angelegt.
+  - Route: `/finance-rules`
+  - Navigation: `Admin -> Finance Regeln`
+  - Zugriff wie andere Admin-Seiten ueber `AdminOnly`.
+- Neue Tabelle/Model `FinanceRules`.
+- Finance-Regeln werden beim Start geseedet und sind danach in der UI pflegbar.
+- Die Regeln wirken auf die Finance-Sicht, nicht auf Rohdaten und nicht auf das technische Spaltenmapping.
+- DE- und IT-Sonderlogik wurde aus dem zentralen Excel-Export in eine generische Regel-Engine verschoben.
+- `ConfigTransferService` exportiert/importiert `FinanceRules` mit.
+- `FinanceReconciliationService` nutzt dieselbe Regel-Engine wie das zentrale Excel, damit Soll/Ist-Vergleich und Endexcel dieselbe Finance-Sicht verwenden.
+- Export Dashboard:
+  - neue Spalte `Basis` direkt nach `Land`
+  - zeigt Datenbasis mit Icon und Text:
+    - `Excel-Datei`
+    - `CSV-Datei`
+    - `SAP Service`
+    - `Server`
+    - `Manuelle Datei`
+
+Aktuelle Default-Finance-Regeln:
+
+- `DE`
+  - Jahr auf `2025` erzwingen fuer das Alphaplan-Jahresfile.
+  - `CustomerName = Trafag AG` ausschliessen.
+  - `CustomerName contains Magnetic Sense` ausschliessen.
+  - `InvoiceNumber = GS2510095` ausschliessen, weil bereits 2024 erfasst.
+  - `InvoiceNumber starts with GS` als negativer Betrag zaehlen.
+- `IT`
+  - `CustomerName contains Trafag Italia` ausschliessen.
+  - doppelte Zeilen ohne `SupplierCountry` deduplizieren.
