Warning

UBL-CR-217: The buyer's address should not have a building name field

In short

Warning: worth checking.

UBL-CR-217 means the buyer's postal address in your UBL file has a separate building name element (BuildingName), which EN 16931 does not use. This is a warning. If you need to keep the building name, put it in an address line, then remove cbc:BuildingName from the buyer's cac:PostalAddress.

What it means

The rule warns if cac:AccountingCustomerParty/cac:Party/cac:PostalAddress in a UBL invoice or credit note contains cbc:BuildingName. In UBL that element holds the name of a building, such as 'Rembrandt Tower'. EN 16931 has no separate field for it.

Why it matters

EN 16931 has no separate building name field. You can keep the building name as address text without including cbc:BuildingName.

How to fix it

If you need to keep the building name, add it to the second address line (BT-51). In XML, use cac:AccountingCustomerParty/cac:Party/cac:PostalAddress/cbc:AdditionalStreetName and preserve any text already there. Delete cbc:BuildingName from the same address, export again and recheck the file.
