Claude	af40d87213	Merge HANA SSL/MDC support and DLL reference fix from claude/blazor-sap-sales-exporter-9VrM0	2026-04-13 09:07:41 +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). Warnung beim Build wenn DLL nicht gefunden wird. https://claude.ai/code/session_012heAXNMbbyxqYf2S2HrKLj	2026-04-10 06:23:59 +00:00

Claude	8524631508	Convert TrafagSalesExporter from console app to Blazor Server app with MudBlazor UI - Replaced console app with .NET 8 Blazor Server architecture - Added EF Core SQLite database (trafag_exporter.db) with auto-seed data - Models: HanaServer, Site, SharePointConfig, ExportSettings, ExportLog, SalesRecord - Services: HanaQueryService (with configurable dateFilter), ExcelExportService, SharePointUploadService, ExportOrchestrationService (with live status events), TimerBackgroundService (scheduled daily export) - MudBlazor UI pages: Dashboard (export status + manual trigger), Standorte (HANA server + site CRUD), Settings (SharePoint + timer config), Logs (filtered view) - SAP HANA queries unchanged (INV + CRN with exact SAP B1 table joins) - SharePoint upload via Microsoft Graph with app registration auth https://claude.ai/code/session_012heAXNMbbyxqYf2S2HrKLj	2026-04-09 14:00:44 +00:00
