Validation rules

UBL-SR-25

The deliver-to party name (BT-70) appears more than once — cac:Delivery may carry only one DeliveryParty/PartyName/Name.

Rule: UBL-SR-25 — official EN 16931 / XRechnung rule
Severity: error
Detected by: tier 3 — KoSIT validator (authoritative)
Reachability: Only reachable when validating your own XML — normbill-generated documents cannot trigger it

The normbill invoice model has no deliver-to party; generated Delivery elements only carry the delivery date.

How to fix it

Keep a single deliver-to party name inside cac:Delivery.

UBL-SR-25 auf Deutsch — was bedeutet der Fehler?

Der KoSIT-Validator lehnt die Rechnung ab, weil der Name des Warenempfängers (BT-70) mehrfach vorkommt — cac:Delivery darf nur einen DeliveryParty/PartyName/Name tragen.

So beheben Sie den Fehler

Behalten Sie genau einen Warenempfänger-Namen innerhalb von cac:Delivery.
