BR-CL-26 — EN 16931 rule

The scheme of a delivery location identifier (BT-71 schemeID) is not part of the ISO/IEC 6523 ICD list.

Rule: BR-CL-26 — 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 invoice model has no delivery location identifier (BT-71) — only the delivery date (BT-72). Fatal in the primary CIUS scenario (only the Extension scenario downgrades it).

How to fix it

Use an ISO 6523 ICD value (e.g. "0088" for GLN) as the schemeID on cac:DeliveryLocation/cbc:ID.

BR-CL-26 auf Deutsch — was bedeutet der Fehler?

Das Schemakennzeichen der Lieferort-Kennung (BT-71, schemeID) stammt nicht aus der ISO/IEC-6523-ICD-Liste. Das normbill-Datenmodell kennt keine Lieferort-Kennung (nur das Lieferdatum, BT-72); KoSIT meldet die Regel nur als Information, die API filtert sie aus dem Report.

So beheben Sie den Fehler

Verwenden Sie einen ICD-Code (z. B. "0088" für GLN) als schemeID an cac:DeliveryLocation/cbc:ID.
