Severity

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

Reconcile the sub-line amounts with the parent invoice line.

BR-DEX-02 auf Deutsch — was bedeutet der Fehler?

Die Nettobeträge der Unterpositionen einer Rechnungsposition sollen sich zum Positionsnetto summieren (Warnung). Diese Regel gehört zur „Extension XRechnung“; normbill erzeugt die reguläre CIUS.

So beheben Sie den Fehler

Gleichen Sie die Unterpositionsbeträge mit der übergeordneten Position ab.
