Warning

UBL-CR-210: The buyer's address should not have an address ID

In short

Warning: worth checking.

UBL-CR-210 means the buyer's postal address in your UBL file has its own identifier, in cbc:ID inside cac:PostalAddress, which EN 16931 does not use. This is a warning. Remove that identifier from the buyer's postal address and keep the normal address fields.

What it means

The rule warns if cac:AccountingCustomerParty/cac:Party/cac:PostalAddress in a UBL invoice or credit note contains cbc:ID. In UBL that element is a code or number that identifies the address itself, for example a reference from an address register. EN 16931 describes the buyer's address with the address lines (BT-50, BT-51, BT-163), city (BT-52), post code (BT-53), country subdivision (BT-54) and country code (BT-55), and has no address identifier.

Why it matters

EN 16931 uses address fields rather than a separate identifier for the buyer's address. This check applies only to cbc:ID directly under the buyer's cac:PostalAddress.

How to fix it

Delete cbc:ID directly under cac:AccountingCustomerParty/cac:Party/cac:PostalAddress, leaving the address fields in place. Do not confuse it with the buyer identifier (BT-46), at cac:AccountingCustomerParty/cac:Party/cac:PartyIdentification/cbc:ID. Export again and recheck the file.
