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:IndustryClassificationCode, a code for the sector the party works in. UBL allows it, but EN 16931 has no business term for it.
Why it matters
EN 16931 has no business term for an industry classification code on the delivery party.
How to fix it
Check whether your invoice export includes a sector, industry or NACE code for the delivery party and omit it from the export. You do not need to delete the code from your customer record to address this rule. If you build the XML yourself, delete cbc:IndustryClassificationCode 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
