What it means
The rule warns if cac:AccountingCustomerParty/cac:Party/cac:PostalAddress in a UBL invoice or credit note contains cbc:Room. In UBL that element holds a room, suite or apartment within a building. EN 16931 has no separate field for it.
Why it matters
EN 16931 has no separate room field. You can keep room, suite or apartment details as address text without including cbc:Room.
How to fix it
If you need to keep the room, suite or apartment, add it to the second address line (BT-51), for example 'Suite 4'. In XML, use cac:AccountingCustomerParty/cac:Party/cac:PostalAddress/cbc:AdditionalStreetName and preserve any text already there. Delete cbc:Room from the same address, export again and recheck the file.
