+
+## 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

+-- 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)

+- `Bestelldatum` - ISO 8601 Format: `YYYY-MM-DDTHH:MM:SS`
+- `Versanddatum` - ISO Date Format: `YYYY-MM-DD` (automatisch berechnet als nächster Arbeitstag)
+
+### Kundenadresse
+- Alle Felder aus der Lieferadresse (`type = 'shipping'`)
+- Leere Werte werden als leere Strings zurückgegeben
+
+### Zahlungsinformationen
+- `Zahlungsart` - Interner Code aus `payment_method` (z.B. `twint`, `bank_transfer`, `card`, `pickup`)
+- Beträge mit 2 Dezimalstellen, NULL wird zu 0
+
+### Produktzählungen
+- Summe der allokierten Mengen pro Produkt
+- Nur aktive Produkte (`status = 'active'`)

+
+### Keine Produkt-Allokationen
+- Alle Produktzählungen sind 0
+- Andere Felder sind normal gefüllt
+
+## Integration in n8n Flow
+
+### Flow-Ablauf
+1. **Webhook Node**: Empfängt `Bestellnummer` vom ERP
+2. **Postgres Node**: Führt diese Query mit `:bestellnummer = $json.Bestellnummer` aus
+3. **Excel Node**: Schreibt das Ergebnis in die Excel-Datei
+4. **Response Node**: Optional - Bestätigung senden
+
+### Query Parameters in n8n
+```
+Query: (siehe oben)
+Query Values: 
+  bestellnummer: {{ $json.Bestellnummer }}
+Operation: Select
+```
+
+## Technische Hinweise
+
+### Performance
+- Query verwendet JOINs auf indizierten Spalten
+- Gruppierung ist effizient für einzelne Bestellungen
+- `COALESCE` verhindert NULL-Werte für Excel-Kompatibilität
+
+### Datum-Logik
+- `shipping_date` wird automatisch via Trigger berechnet
+- Wochenend-Logik: Freitag → Montag, Samstag → Montag, Sonntag → Montag
+- Keine Feiertags-Logik in Phase 1
+
+### Schema-Konsistenz
+- Alle Tabellen existieren nach Migration 0007
+- `shipping_date` kann NULL sein (für sehr alte Bestellungen)
+- Produkt-IDs sind statisch in der aktuellen DB
+
+## Testing
+
+### Test Query
+```sql
+-- Test mit existierender Bestellung
+SELECT * FROM sales_order WHERE external_ref LIKE 'W%' OR external_ref LIKE 'DIR-%' LIMIT 5;
+
+-- Test Query mit konkreter Bestellnummer
+-- [Hier Query einfügen und :bestellnummer ersetzen]
+```
+
+### Expected Results
+- Eine Zeile pro Bestellung
+- Alle Felder gefüllt oder leere Strings/0
+- Produktzählungen als Ganzzahlen
