Validation rules

BR-17 — EN 16931 rule

A payee (BG-10) that differs from the seller must state the payee name (BT-59).

Rule: BR-17 — official EN 16931 / XRechnung rule
Severity: error
Business term: BT-59
Detected by: tier 3 — KoSIT validator (authoritative)
Reachability: Not expressible through the normbill invoice model — documented for completeness

The normbill invoice model has no payee party (BG-10) — payment always goes to the seller — so generated documents cannot contain this construct.

How to fix it

Add cac:PartyName/cbc:Name to cac:PayeeParty, or remove the payee party when the seller is paid directly.

BR-17 auf Deutsch — was bedeutet der Fehler?

Ein vom Verkäufer abweichender Zahlungsempfänger (BG-10) ist angegeben, aber sein Name (BT-59) fehlt.

So beheben Sie den Fehler

Ergänzen Sie cac:PartyName/cbc:Name in cac:PayeeParty — oder entfernen Sie die Partei, wenn direkt an den Verkäufer gezahlt wird.
