## Produkt-Mapping
|
|
|
|
| Excel-Feld | Produkt-ID | SKU | Status |
|
|
|------------|------------|-----|--------|
|
|
| `#_ChagaFlaschen` | 8 | `CHAGA` | aktiv |
|
|
| `#_ReishiFlaschen` | 5 | `003.01` | aktiv |
|
|
| `#_ShiitakeFlaschen` | 9 | `SHIITAKE` | aktiv |
|
|
| `#_LionsManeFlaschen` | 6 | `005.02` | aktiv |
|
|
|
|
**Ignoriert:** ID 7 (`LIONSMANE`) - inaktiv
|
|
|
|
## Fehlerbehandlung
|
|
|
|
### Keine Bestellung gefunden
|
|
- Alle Felder werden als leere Strings oder 0 zurückgegeben
|
|
- Excel-Node kann trotzdem ausgeführt werden
|
|
|
|
### Keine Produkt-Allokationen
|
|
- Produktzählungen sind 0
|
|
- Andere Felder sind normal gefüllt
|
|
|
|
## Testing
|
|
|
|
### Test Query direkt in DB
|
|
```bash
|
|
psql "postgresql://codex_db_user:Ze90re0KAry8gyJ6eAx0Gf4IelEGI@192.168.1.199:55432/naurua_erp" -c "
|
|
-- Test mit existierender Bestellung
|
|
SELECT external_ref FROM sales_order WHERE external_ref LIKE '10%' LIMIT 1;"
|
|
```
|
|
|
|
### Test Response
|
|
Erwartet eine Zeile mit allen Feldern gefüllt oder als leere Strings/0.
|
|
|
|
## Wichtige Hinweise
|
|
|
|
1. **shipping_date** wird automatisch via Trigger berechnet (nächster Arbeitstag)
|
|
2. **Wochenend-Logik**: Freitag → Montag, Samstag → Montag, Sonntag → Montag
|
|
3. **Feldnamen** müssen exakt wie oben angegeben sein (Groß-/Kleinschreibung beachten)
|
|
4. **Produkt-IDs** sind fest in der Query hinterlegt
|
|
5. **Max Rows** = 1 (eine Bestellung pro Aufruf) |
