UBL-CR-181
What does UBL-CR-181 mean? A UBL invoice should not include the AccountingSupplierParty Party PartyLegalEntity SoleProprietorshipIndicator
Why did my invoice fail UBL-CR-181?
This EN 16931 rule warns when the UBL element cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:SoleProprietorshipIndicator is present: the invoice should not include a sole proprietorship indicator for the seller. The core model does not describe the corporate structure of the seller beyond the legal name, registration ID and free-text legal information (BT-33), so this indicator has no mapped business term. 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.

Common causes
- ERP exports every boolean flag from its company master record
- Schema-driven generator populating all optional PartyLegalEntity fields
- Mapping from a national format that distinguished sole proprietors explicitly
