Warning

UBL-CR-529: A line should not point to a despatch advice line

In short

Warning: worth checking.

UBL-CR-529 means an invoice or credit note line contains a despatch advice line reference (cac:DespatchLineReference), which EN 16931 does not use. It is a warning; remove the line reference and recheck the file.

On this page

What it means

The rule warns when any cac:InvoiceLine or cac:CreditNoteLine contains cac:DespatchLineReference, a reference to a line of a despatch advice or delivery note. It does not check the document-level despatch advice reference (BT-16).

Why it matters

The data model has no place for a per-line despatch reference. It is worth fixing when the buyer matches deliveries to lines.

How to fix it

Remove the despatch advice line reference from each affected line. If you need to give a despatch advice number, use the document-level despatch advice reference (BT-16). If the line number matters, add it to the line note (BT-127). In the XML, delete cac:DespatchLineReference from cac:InvoiceLine (cac:CreditNoteLine in a credit note). Recheck the 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
