What does UBL-CR-323 mean? A UBL invoice should not include the TaxRepresentativeParty PostalAddress Country Name

Why did my invoice fail UBL-CR-323?

The invoice should not contain the country Name element inside the tax representative's postal address (cac:TaxRepresentativeParty/cac:PostalAddress/cac:Country/cbc:Name). EN 16931 identifies the country solely by its code (BT-69, cbc:IdentificationCode); a textual country name is outside the core model and is redundant next to the code.

Official rule text

Common causes

The generator emits both the ISO country code and a human-readable country name
Mapping software copies a full country object (code + name) from the ERP into the UBL Country element
