What it means
This rule checks that the seller (BG-4) does not carry cbc:AdditionalAccountID directly inside cac:AccountingSupplierParty in a UBL invoice or credit note. That element is an extra account identifier for the seller. It is not your bank account. Bank details belong in the payment instructions (BG-16).
Why it matters
EN 16931 does not use this additional account-ID element in the seller details.
How to fix it
Remove cbc:AdditionalAccountID from cac:AccountingSupplierParty. If it is a number the buyer needs, such as your VAT number or company registration number, check that it is entered in its own field. Export the corrected file and check it again.
Once the file is corrected, check it again for free: Validate an invoice against EN 16931
Or fix the invoice in a form and download the corrected file, for 1 credit: Fix a rejected e-invoice
