What it means
This rule checks that the buyer's tax details, the element cac:PartyTaxScheme, do not contain cbc:RegistrationName. EN 16931 maps the buyer's VAT number (BT-48) to the tax block and the buyer's name (BT-44) to cac:PartyLegalEntity/cbc:RegistrationName. This rule concerns RegistrationName in the tax block, not the name in the legal entity block. It applies to UBL invoices and credit notes.
Why it matters
EN 16931 places the buyer's name (BT-44) in the legal entity block, not the tax block.
How to fix it
Check the buyer's record in your invoicing software. The buyer's name should be in the name field, and the VAT number in the VAT number field. Make sure the export omits RegistrationName from the buyer's PartyTaxScheme. If you build the XML yourself, delete cbc:RegistrationName from cac:AccountingCustomerParty/cac:Party/cac:PartyTaxScheme and keep the name in the buyer's cac:PartyLegalEntity/cbc:RegistrationName. Export or save the file again and recheck it.
