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

Der bereits gezahlte Betrag (BT-113) hat mehr als 2 Nachkommastellen. EN 16931 erlaubt höchstens 2 Dezimalstellen — der KoSIT-Validator lehnt die Rechnung ab.

So beheben Sie den Fehler

Runden Sie cbc:PrepaidAmount / invoice.paid_amount auf 2 Nachkommastellen. normbill schreibt PrepaidAmount und PayableAmount = BT-112 − BT-113, wenn paid_amount gesetzt ist.
