Warning

UBL-CR-660: Country codes should have no listID attribute

In short

Warning: worth checking.

UBL-CR-660 means a cbc:IdentificationCode inside cac:Country has a listID attribute, which EN 16931 does not use. Remove the attribute and keep the two-letter country code.

On this page

What it means

This rule checks every cbc:IdentificationCode inside cac:Country anywhere in the file and flags any listID attribute. These elements carry two-letter country codes, such as DE, FR or NL, including those for the seller (BT-40), the buyer (BT-55), the delivery address (BT-80) and the tax representative (BT-69). EN 16931 fixes the code list (ISO 3166-1), so naming it with listID is not used.

Why it matters

EN 16931 does not use listID on cbc:IdentificationCode inside cac:Country. This warning concerns the attribute, not the country code value.

How to fix it

Remove listID from every cbc:IdentificationCode inside cac:Country and keep the country codes unchanged. If your software adds the attribute, ask its supplier to correct the export, then check the new file again.
