Validation rules

BR-DEX-14

A third-party payment amount must use the invoice currency (BT-5) as its currency.

Rule: BR-DEX-14 — 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

Belongs to the 'Extension XRechnung' CustomizationID. normbill generates the plain CIUS, never the Extension — reachable only for Extension XML submitted to /v1/invoices/validate.

How to fix it

Align the third-party amount's currencyID with the invoice currency.

BR-DEX-14 auf Deutsch — was bedeutet der Fehler?

Ein Fremdforderungsbetrag muss die Rechnungswährung (BT-5) verwenden. Diese Regel gehört zur „Extension XRechnung“; normbill erzeugt die reguläre CIUS.

So beheben Sie den Fehler

Gleichen Sie die currencyID des Betrags an die Rechnungswährung an.
