What it means
The check requires UltimatePayeeTradeParty to be absent directly under ApplicableHeaderTradeSettlement. The supported payee group (BG-10) is separate from this ultimate payee element.
Why it matters
EN 16931 provides a payee role but no separate ultimate payee role. An ultimate payee is not necessarily the party you should identify as the payment recipient.
How to fix it
Remove UltimatePayeeTradeParty from ApplicableHeaderTradeSettlement. If payment goes to someone other than the seller, record that party in PayeeTradeParty (BG-10). Do not transfer the ultimate payee's details without checking that they identify the actual payment recipient. Recheck your file.
