- Not expressible through the normbill invoice model — documented for completeness
The pinned Schematron implements this as an always-true assertion, so the validator never reports it in practice.
How to fix it
Align the charge's reason and reason_code so they describe the same thing.
BR-CO-06 auf Deutsch — was bedeutet der Fehler?
Der Code des Zuschlagsgrundes (BT-105) und der Grundtext (BT-104) sollen denselben Zuschlagstyp beschreiben. Die amtliche Schematron-Implementierung prüft dies faktisch nicht.
So beheben Sie den Fehler
Bringen Sie reason und reason_code des Zuschlags inhaltlich in Übereinstimmung.
