UBL-SR-14: Seller additional legal information can be given only once

In short

Fatal: fails the selected checks.

UBL-SR-14 means the invoice has more than one additional legal information field for the seller (BT-33). Merge them into one short text and export the invoice again.

What it means

The seller's additional legal information (BT-33) is a free-text field for company details that have no field of their own, such as the legal form or the share capital. In UBL it is cbc:CompanyLegalForm in the seller's cac:PartyLegalEntity. The rule counts those elements and allows one.

Why it matters

EN 16931 allows at most one seller additional legal information field per invoice or credit note.

How to fix it

Find the field for the company footer, legal form or extra company details in your invoicing software, and combine everything into one field. Make sure the text is not entered in two places that are both exported. In the XML, keep one cbc:CompanyLegalForm in cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity.
