BR-CL-16 — EN 16931 rule

The payment means code (BT-81) is not a UNTDID 4461 code.

Rule: BR-CL-16 — official EN 16931 / XRechnung rule
Severity: error
Business term: BT-81 — Payment means code
Field in your JSON: invoice.payment.means_code

How to fix it

Set invoice.payment.means_code to a UNTDID 4461 value — 58 (SEPA credit transfer) or 30 (credit transfer) cover most invoices — or omit it and let normbill pick the default.

BR-CL-16 auf Deutsch — was bedeutet der Fehler?

Der Code der Zahlungsart (BT-81) stammt nicht aus der UNTDID 4461. Das Eingabeschema verlangt nur ein bis drei Ziffern — ein Code wie "999" passiert die Prüfung und wird erst vom KoSIT-Validator abgelehnt.

So beheben Sie den Fehler

Setzen Sie invoice.payment.means_code auf einen UNTDID-4461-Code — 58 (SEPA-Überweisung) oder 30 (Überweisung) decken die meisten Fälle ab. Oder lassen Sie das Feld weg, dann wählt normbill automatisch.
