What to do now
Who has to fix this?
The issuer of the invoice has to fix this. Usually an internal code was passed on unchanged instead of being mapped to the standard value.
Where this rule comes from
BR-CL rules check whether a coded value comes from the prescribed code list — for example currencies according to ISO 4217, countries according to ISO 3166-1, units of measure according to UN/ECE Rec 20 or payment means according to UNTDID 4461. Free text is not allowed in these places.
