Warning

UBL-CR-387: Leave out the 'mark for attention' flag on the delivery party

In short

Warning: worth checking.

UBL-CR-387 means the delivery party carries a 'mark for attention' flag (cbc:MarkAttentionIndicator), which EN 16931 does not use. Remove cbc:MarkAttentionIndicator from cac:Delivery/cac:DeliveryParty.

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 cbc:MarkAttentionIndicator. The test checks for the element's presence, regardless of its value.

Why it matters

EN 16931 does not use cbc:MarkAttentionIndicator in the delivery party information.

How to fix it

Change your invoice export so it omits cbc:MarkAttentionIndicator from the delivery party. If you cannot change the export, ask your software supplier to stop exporting that element. If you build the XML yourself, delete cbc:MarkAttentionIndicator from cac:Delivery/cac:DeliveryParty. Recheck the exported file.
