UBL-CR-606
What does UBL-CR-606 mean? A UBL invoice should not include the InvoiceLine Item ClassifiedTaxCategory TaxScheme CurrencyCode
Why did my invoice fail UBL-CR-606?
The official rule states: "A UBL invoice should not include the InvoiceLine Item ClassifiedTaxCategory TaxScheme CurrencyCode". The CurrencyCode element under InvoiceLine/Item (Item/ClassifiedTaxCategory/TaxScheme) 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. In EN 16931 the line VAT information (BG-30) is limited to the category code (cbc:ID) and rate (cbc:Percent), with the tax scheme identified only by cac:TaxScheme/cbc:ID (normally "VAT").
Official rule text
A UBL invoice should not include the InvoiceLine Item ClassifiedTaxCategory TaxScheme CurrencyCode
Common causes
- An ERP or accounting export serialises its full internal tax-scheme record instead of only the scheme ID
- Reusing a UBL template from a non-EN 16931 context (e.g. a national extension) that populates extra TaxScheme children
- A generic UBL library emitting every optional field by default
