BR-DE-3BT-37
input
The seller city is missing
The `Seller city` element (BT-37) must be provided.
Only the issuer holds this value: Factlint reports it and never fabricates it. Test your invoice to find out whether it is affected.
Why this error happens
EN 16931 reduces the seller's postal address to the country; XRechnung adds the city and the post code. A truncated address therefore passes European validation and fails here, with nothing having changed in the document.
How to fix it
Complete the seller's address in your master data. The city does not follow from the post code: several towns share one.
