Validation rules

BR-DEX-15

This CII document appears to use sub-invoice lines, which XRechnung does not support in this syntax.

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

Remove the sub-invoice lines, or use the UBL syntax with the Extension.

BR-DEX-15 auf Deutsch — was bedeutet der Fehler?

Dieses CII-Dokument scheint Unterpositionen zu verwenden, die die XRechnung in dieser Syntax nicht unterstützt (Warnung). Diese Regel gehört zur „Extension XRechnung“; normbill erzeugt die reguläre CIUS.

So beheben Sie den Fehler

Entfernen Sie die Unterpositionen — oder nutzen Sie UBL mit der Extension.
