Error

FX-SCH-A-000409: The seller must have exactly one name

In short

Error: fails the selected checks.

FX-SCH-A-000409 means the seller block (BG-4) contains either no ram:Name element or more than one for the seller name (BT-27). Correct the seller details or XML export so that the block contains exactly one ram:Name, then recheck the file.

What it means

This rule requires exactly one ram:Name directly inside each ram:SellerTradeParty in the header trade agreement. It applies in the Minimum, BASIC WL, Basic, EN 16931 and Extended profiles of Factur-X and ZUGFeRD. It checks the number of name elements, not their text.

Why it matters

The seller name identifies the party supplying the goods or services. A single name element keeps that identification in one place.

How to fix it

Check the seller's name (BT-27) in your invoice data. Do not assume the seller is your own business, particularly if you issue a self-billed invoice. In the XML, add the missing ram:Name or remove duplicate name elements directly under the header ram:SellerTradeParty. If your software exports the wrong structure despite correct details, ask its supplier to correct it. Export and recheck the file.
