Warning

UBL-CR-327: No tax level code for the tax representative

In short

Warning: worth checking.

UBL-CR-327 means the tax details of the seller's tax representative contain a tax level code (cbc:TaxLevelCode), which EN 16931 does not use. Remove the code to clear the warning.

On this page

What it means

The tax details of the seller's tax representative (BG-11) are limited to its VAT number (BT-63) and the tax scheme, which must be VAT. The rule flags a cbc:TaxLevelCode inside cac:PartyTaxScheme. In UBL this is a code for the tax level or regime a party falls under, and EN 16931 has no field for it. It applies to invoices and credit notes.

Why it matters

EN 16931 does not use a tax level code in the tax representative's tax details.

How to fix it

Remove cbc:TaxLevelCode from cac:TaxRepresentativeParty/cac:PartyTaxScheme in the exported XML. Do not clear unrelated tax fields to remove this warning. If your software adds the element automatically, ask the vendor how to omit it. Recheck the exported file.
