UBL-CR-603
What does UBL-CR-603 mean? A UBL invoice should not include the InvoiceLine Item ClassifiedTaxCategory TierRatePercent
Why did my invoice fail UBL-CR-603?
The official rule states: "A UBL invoice should not include the InvoiceLine Item ClassifiedTaxCategory TierRatePercent". The TierRatePercent element under InvoiceLine/Item (Item/ClassifiedTaxCategory) exists in the generic UBL 2.1 schema but is not mapped to any EN 16931 business term, so a core-compliant invoice must leave it out. Receivers validating against EN 16931 will flag it because data in unmapped elements cannot be reliably processed. EN 16931 restricts the line VAT information (BG-30) to the category code (cbc:ID) and VAT rate (cbc:Percent); exemption reasons belong at document level in the VAT breakdown (BG-23), not on the line.
Official rule text
A UBL invoice should not include the InvoiceLine Item ClassifiedTaxCategory TierRatePercent
Common causes
- Placing VAT exemption reason text or codes on the invoice line instead of in the document-level VAT breakdown (cac:TaxTotal/cac:TaxSubtotal/cac:TaxCategory)
- A UBL generator populating every optional child of cac:ClassifiedTaxCategory
- Reusing a template from a non-EN 16931 UBL profile
