Warning

UBL-CR-132: Supporting documents should not name an issuing party

In short

Warning: worth checking.

UBL-CR-132 means an additional document reference in your UBL invoice or credit note names the party that issued the document (IssuerParty), which EN 16931 does not use there. Remove that element. For a supporting document, you can name the issuer in the document description (BT-123).

What it means

This rule checks that no document-level cac:AdditionalDocumentReference contains cac:IssuerParty in a UBL invoice or credit note. For supporting documents (BG-24), the reference holds an identifier (BT-122), an optional description (BT-123) and optionally a link or the file itself. The check applies to every additional document reference.

Why it matters

EN 16931 does not use a separate issuing-party element in an additional document reference.

How to fix it

Remove cac:IssuerParty from cac:AdditionalDocumentReference. If the issuer of a supporting document matters, add it to the supporting document description (BT-123), for example the name of the authority or company. Export the corrected file and check it again.

Once the file is corrected, check it again for free: Validate an invoice against EN 16931

Or fix the invoice in a form and download the corrected file, for 1 credit: Fix a rejected e-invoice
