BR-4

Seller Name Missing (BT-27)

What This Error Means

The seller's legal name (BT-27) must be present in cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:RegistrationName. This is the full registered company name, not a trading name or abbreviation.

How to Fix It

Add the full legal company name to cbc:RegistrationName under cac:PartyLegalEntity. This should match your Handelsregister entry exactly.

XML Example
<cac:PartyLegalEntity>
  <cbc:RegistrationName>Muster GmbH</cbc:RegistrationName>
  <cbc:CompanyID>HRB 123456</cbc:CompanyID>
</cac:PartyLegalEntity>
