Warning

UBL-CR-333: No currency code in the tax representative's tax scheme

In short

Warning: worth checking.

UBL-CR-333 means the tax scheme of the seller's tax representative has a currency code (cbc:CurrencyCode), which EN 16931 does not use there. The invoice currency is given once for the whole document, so remove this one.

On this page

What it means

The rule flags a cbc:CurrencyCode in the cac:TaxScheme block. The currency of the invoice is set once, as the invoice currency code (BT-5), and the tax scheme block has no field for a currency of its own. It applies to invoices and credit notes.

Why it matters

EN 16931 does not use a currency code in the tax representative's tax scheme.

How to fix it

Remove cbc:CurrencyCode from cac:TaxRepresentativeParty/cac:PartyTaxScheme/cac:TaxScheme in the exported XML. Do not remove the invoice currency code (BT-5) to clear this warning. If your software adds the tax scheme currency automatically, ask the vendor how to omit it. Recheck the exported file.
