What it means
This rule checks the buyer's legal entity block in a UBL invoice or credit note (cac:AccountingCustomerParty, cac:Party, cac:PartyLegalEntity). It must not contain cbc:CompanyLegalForm, free text such as the buyer's company type. EN 16931 has a free-text field for extra legal information about the seller (BT-33), but none for the buyer.
Why it matters
The rule excludes the separate legal form text from the buyer's legal entity details. It does not require you to change the buyer's name.
How to fix it
Configure your UBL export to omit the buyer's separate legal form text, without changing the buyer's name. If you edit or generate the XML, remove cbc:CompanyLegalForm from cac:AccountingCustomerParty/cac:Party/cac:PartyLegalEntity. Recheck the file in Klarbon.
