What it means
This rule checks that cac:PaymentMeans/cac:PaymentMandate contains no cac:PaymentReversalPeriod block. It does not assess the conditions under which a payment can be reversed.
Why it matters
EN 16931 does not use a payment reversal period block in its UBL mandate details.
How to fix it
Remove cac:PaymentReversalPeriod from cac:PaymentMeans/cac:PaymentMandate. Keep the mandate reference (BT-89) in cbc:ID. If your software exports the block automatically, ask its supplier to omit it from the XML rather than deleting reversal or refund conditions from your records. Recheck the file.
