Validation rules

BR-CO-07

An invoice line allowance reason code (BT-140) and reason text (BT-139) should describe the same type of allowance.

Rule: BR-CO-07 — official EN 16931 / XRechnung rule
Severity: error
Detected by: tier 3 — KoSIT validator (authoritative)
Reachability: 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 line allowance's reason and reason_code so they describe the same thing.

BR-CO-07 auf Deutsch — was bedeutet der Fehler?

Code (BT-140) und Text (BT-139) des Grundes eines Positionsnachlasses sollen denselben Typ beschreiben. Die amtliche Schematron-Implementierung prüft dies faktisch nicht.

So beheben Sie den Fehler

Bringen Sie reason und reason_code des Positionsnachlasses in Übereinstimmung.
