Warning

UBL-CR-398: Leave out the contact details of the delivery party

In short

Warning: worth checking.

UBL-CR-398 means the delivery party has contact details (cac:Contact), which EN 16931 does not use there. Remove cac:Contact from cac:Delivery/cac:DeliveryParty. If the delivery contact details need to remain on the invoice, put them in the invoice note (BT-22).

What it means

This rule looks at the delivery party (cac:DeliveryParty), the party the goods or services go to, in the delivery information of a UBL invoice or credit note. It checks that the party has no cac:Contact, which holds a contact name, telephone number and email address. EN 16931 has contact details only for the seller (BG-6) and the buyer (BG-9).

Why it matters

EN 16931 defines contact fields for the seller (BG-6) and the buyer (BG-9), not for the delivery party.

How to fix it

Omit the delivery party's contact block from your invoice export. If the delivery contact matters, add it to the invoice note (BT-22). Use the buyer contact (BG-9) only if the details also belong to the buyer's contact. If you build the XML yourself, delete cac:Contact from cac:Delivery/cac:DeliveryParty. Recheck the exported file.
