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:ServiceProviderParty, a service provider for that party. UBL allows it, but EN 16931 has no business term for it.
Why it matters
EN 16931 has no field for a service provider on the delivery party. Removing cac:ServiceProviderParty from that location addresses this warning.
How to fix it
Remove cac:ServiceProviderParty from cac:Delivery/cac:DeliveryParty in your XML export. If the buyer needs the information, write it in the invoice note (BT-22). 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
