Peppol BIS Billing 3.0.20 · UBL
Original rule text
[UBL-CR-558]-A UBL invoice should not include the InvoiceLine AllowanceCharge TaxCategory
not((cac:InvoiceLine|cac:CreditNoteLine)/cac:AllowanceCharge/cac:TaxCategory)UBL-CR-558 is a warning rule in the schema layer of Peppol BIS Billing 3.0.20 · UBL. An invoice that breaks it is flagged but not rejected.
What this rule requires
The rule checks that no cac:InvoiceLine or cac:CreditNoteLine contains a cac:AllowanceCharge with a cac:TaxCategory. If any such cac:TaxCategory is present, the condition not(...) is false and the warning is reported. Since severity is warning, the document is not rejected, but the rule advises against including a tax category at the line-level allowance/charge.
How to fix
Remove the cac:TaxCategory element from any cac:AllowanceCharge inside cac:InvoiceLine or cac:CreditNoteLine. Keep line-level allowances/charges without a tax category, or move tax information to an element where the rule permits it.
