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:WebsiteURI. UBL allows a website address there, but EN 16931 has no business term for it.
Why it matters
EN 16931 has no business term for a website address on the delivery party.
How to fix it
Configure your invoice export to omit the delivery party's cbc:WebsiteURI. If a website matters to the buyer, it can go in the invoice note (BT-22) or in the layout of the PDF. If you build the XML yourself, delete cbc:WebsiteURI from cac:Delivery/cac:DeliveryParty. Recheck the exported 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
