Warning

UBL-CR-118: Leave the version out of additional document references

In short

Warning: worth checking.

UBL-CR-118 means an additional document reference in your UBL invoice or credit note carries a version (cbc:VersionID), which EN 16931 does not use. Delete that element from cac:AdditionalDocumentReference and keep the other details.

On this page

What it means

This rule checks that no cac:AdditionalDocumentReference in a UBL invoice or credit note contains cbc:VersionID, the version identifier of the referenced document. It applies to all additional document references, including supporting documents (BG-24).

Why it matters

EN 16931 recommends leaving the version identifier out of additional document references.

How to fix it

Delete cbc:VersionID from cac:AdditionalDocumentReference, or ask your invoicing software supplier to stop exporting it there. If the reference is for a supporting document and its version matters, include it in the description (BT-123), for example Timesheet, version 2. Recheck the corrected file.

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
