tier 3 — KoSIT validator (authoritative)
Reachability
Only reachable when validating your own XML — normbill-generated documents cannot trigger it

The serializer emits at most one PaymentID, from invoice.payment.reference.

How to fix it

Use one payment reference for the whole invoice; repeat the identical value if several PaymentMeans need it.

UBL-SR-44 auf Deutsch — was bedeutet der Fehler?

Der KoSIT-Validator lehnt die Rechnung ab, weil das Dokument mehrere unterschiedliche cbc:PaymentID-Werte trägt — der Verwendungszweck (BT-83) muss eindeutig sein; derselbe Wert darf auf mehreren Zahlungswegen wiederholt werden.

So beheben Sie den Fehler

Verwenden Sie einen Verwendungszweck für die gesamte Rechnung; wiederholen Sie bei mehreren PaymentMeans denselben Wert.
