What it means
The rule looks at the item on every invoice line (or credit note line) in a UBL file. It warns when the item contains a cac:TransactionConditions block, which holds conditions that apply to the sale of that item. EN 16931 has no such block on a line. It has the invoice note (BT-22), the invoice line note (BT-127) and the payment terms (BT-20).
Why it matters
EN 16931 does not use transaction condition blocks within a line's item.
How to fix it
Check your invoicing software for a per-product conditions or terms field that is exported on the line, and switch that export off. Write any condition that matters in the line note or the invoice note, and keep payment conditions in the payment terms. If you build the XML yourself, delete cac:TransactionConditions from cac:InvoiceLine/cac:Item (cac:CreditNoteLine in a credit note).
