UBL-CR-171
What does UBL-CR-171 mean? A UBL invoice should not include the AccountingSupplierParty Party PartyTaxScheme ExemptionReasonCode
Why did my invoice fail UBL-CR-171?
This EN 16931 rule warns when the UBL element cac:AccountingSupplierParty/cac:Party/cac:PartyTaxScheme/cbc:ExemptionReasonCode is present: the invoice should not include an exemption reason code inside the seller's tax registration (PartyTaxScheme). In EN 16931, VAT exemption reasons belong to the VAT breakdown (BT-121 in BG-23), not to the seller party; a party-level ExemptionReasonCode 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.
Official rule text
A UBL invoice should not include the AccountingSupplierParty Party PartyTaxScheme ExemptionReasonCode
Common causes
- Exemption information was mapped to the seller party instead of the TaxCategory in the TaxSubtotal
- A generic UBL 2.1 template exposes every PartyTaxScheme child element
- ERP export fills seller tax fields wholesale from its master data
