What it means
This rule checks that cac:PaymentMeans contains no cac:TradeFinancing block. It applies to invoices and credit notes and does not assess the financing arrangement itself.
Why it matters
EN 16931 does not use this trade financing block within its UBL payment instructions (BG-16). This does not mean that every reference to a financing arrangement is prohibited.
How to fix it
Remove cac:TradeFinancing from cac:PaymentMeans in the XML export. If the arrangement includes payment conditions you need to state on the invoice, describe those conditions in the payment terms text (BT-20). Do not switch off the underlying financing arrangement just to clear this warning. Recheck the file.
