Warning

UBL-CR-056: The despatch reference should not include a description

In short

Warning: worth checking.

UBL-CR-056 means the despatch advice reference contains a document description, which EN 16931 does not use. Remove cbc:DocumentDescription from cac:DespatchDocumentReference.

On this page

What it means

The despatch advice reference (BT-16) points at the despatch advice, the document that lists what was sent. In a UBL invoice or credit note it is cac:DespatchDocumentReference. This rule checks that the block does not contain a free-text description of the referenced document (cbc:DocumentDescription).

Why it matters

EN 16931 does not use a description inside the despatch advice reference.

How to fix it

Remove the description from the despatch advice reference. If the text matters to the buyer, put it in the invoice note (BT-22). If you build the XML yourself, delete cbc:DocumentDescription from cac:DespatchDocumentReference. Then check the file 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
