What does UBL-CR-331 mean? A UBL invoice should not include the TaxRepresentativeParty PartyTaxScheme TaxScheme Name

Why did my invoice fail UBL-CR-331?

The invoice should not contain the Name element inside the tax representative's TaxScheme (cac:TaxRepresentativeParty/cac:PartyTaxScheme/cac:TaxScheme/cbc:Name). EN 16931 identifies the tax scheme by its code in cbc:ID (the value VAT for the representative's VAT identifier BT-63); a textual scheme name is outside the core model.

Official rule text

A UBL invoice should not include the TaxRepresentativeParty PartyTaxScheme TaxScheme Name

Common causes

The generator emits both cbc:ID and a descriptive cbc:Name for the tax scheme
A full TaxScheme object is serialised from a code list that stores code plus label

How do I fix it?

<cac:TaxScheme>
  <cbc:ID>VAT</cbc:ID>
</cac:TaxScheme>
<!-- remove <cbc:Name>Value added tax</cbc:Name> -->
