UBL-CR-173
What does UBL-CR-173 mean? A UBL invoice should not include the AccountingSupplierParty Party PartyTaxScheme RegistrationAddress
Why did my invoice fail UBL-CR-173?
This EN 16931 rule warns when the UBL element cac:AccountingSupplierParty/cac:Party/cac:PartyTaxScheme/cac:RegistrationAddress is present: the invoice should not include a registration address inside the seller's tax registration (PartyTaxScheme). EN 16931 models the seller's address once, as the postal address (BG-5) under cac:PostalAddress; a separate tax registration address is not part of the core model. 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.
Official rule text
A UBL invoice should not include the AccountingSupplierParty Party PartyTaxScheme RegistrationAddress
Common causes
- The seller's address was duplicated into the tax scheme block by the mapping
- A UBL 2.1 sample with a fully populated PartyTaxScheme was used as a template
- Legacy national format required a tax registration address and the converter kept it
