What it means
Checks that no ram:ReceivableSpecifiedTradeAccountingAccount under ram:ApplicableHeaderTradeSettlement contains a ram:SetTriggerCode child.
Why it matters
SetTriggerCode is not part of the EN 16931 CII representation of the invoice-level buyer accounting reference (BT-19). This warning does not establish recipient acceptance.
How to fix it
Remove ram:SetTriggerCode only from ram:ReceivableSpecifiedTradeAccountingAccount in the header settlement. Keep ram:ID if you use it for the buyer accounting reference (BT-19). If your software adds the code, ask your software supplier to correct the export. Recheck the file.
