Warning

UBL-CR-408: The delivery should not contain a maximum delivery unit

In short

Warning: worth checking.

UBL-CR-408 means the UBL file states a maximum delivery unit in the delivery information (cac:MaximumDeliveryUnit), which EN 16931 does not use. Remove it and export again.

On this page

What it means

The check looks at the delivery information (BG-13) of the invoice or credit note and warns when it contains cac:Delivery/cac:MaximumDeliveryUnit, the largest unit in which the goods may be delivered. This is ordering and logistics information, and EN 16931 has no field for it. The invoiced quantity (BT-129) sits on the invoice lines.

Why it matters

The EN 16931 UBL mapping does not include a maximum delivery unit in the delivery information. This is separate from the quantity invoiced on each line.

How to fix it

Delete cac:MaximumDeliveryUnit from cac:Delivery in your XML export. Keep the invoiced quantity (BT-129) on the lines. 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
