What does UBL-CR-193 mean? A UBL invoice should not include the AccountingSupplierParty Party Person

Why did my invoice fail UBL-CR-193?

This EN 16931 rule warns when the UBL element cac:AccountingSupplierParty/cac:Party/cac:Person is present: the invoice should not include a Person structure under the seller party. EN 16931 has no person-level detail for the seller; individual contact information is carried in the seller contact (BG-6) via cac:Contact, and the trading name/legal name cover naming. The element is not forbidden by UBL itself, but it lies outside the EN 16931 core invoice model, so remove it to keep the invoice fully conformant and interoperable.

Full UBL 2.1 schema export enabling the Person structure
Sole trader details mapped as a person rather than as the party name
