Official rule text

Das Element "Seller city" (BT-37) muss übermittelt werden.

Why it happens

The address often exists internally as one combined address line. Without clean separation into street, post code and city, the structured city field stays empty.

How to fix it

Send the city in BT-37: cac:PostalAddress/cbc:CityName in UBL, ram:PostalTradeAddress/ram:CityName in CII. Split addresses into individual fields once, in the master data.
