Validation rules

BR-DE-CVD-04

A CVD item classification (BT-158, scheme 'CVD') must use one of the permitted vehicle category codes.

Rule: BR-DE-CVD-04 — official EN 16931 / XRechnung rule
Severity: error
Detected by: tier 3 — KoSIT validator (authoritative)
Reachability: Only reachable when validating your own XML — normbill-generated documents cannot trigger it

Belongs to the 'XRechnung CVD' sibling CIUS (Clean Vehicle Directive) — a separate CustomizationID normbill never generates; reachable only for CVD XML submitted to /v1/invoices/validate.

How to fix it

Use a value from the CVD vehicle-category list.
