What it means
This rule checks that cac:PaymentTerms contains no cbc:PaymentPercent element. It does not check the instalment schedule, due date (BT-9) or amount due (BT-115).
Why it matters
EN 16931 does not use this structured payment percentage within UBL payment terms.
How to fix it
Remove cbc:PaymentPercent from cac:PaymentTerms. If you have agreed instalments, describe their proportions and deadlines in cbc:Note (BT-20). Do not change the due date (BT-9) or amount due (BT-115) merely to clear this warning. Recheck the file.
