FX-SCH-A-001137: Reason code for a line discount must be a valid code

In short

Error: fails the selected checks.

FX-SCH-A-001137 means a non-empty reason code for an invoice line discount (BT-140) is not allowed. Correct ram:ReasonCode using the Extended profile's permitted discount reason codes.

What it means

The rule checks ram:ReasonCode in a line discount (BG-27) against code list 28. It applies under ram:SpecifiedLineTradeSettlement/ram:SpecifiedTradeAllowanceCharge only when ram:ChargeIndicator/udt:Indicator has the value false. An empty reason code passes.

Why it matters

A recognised reason code lets software identify the stated reason for the line discount.

How to fix it

Check the reason for the affected line discount and correct ram:ReasonCode in its ram:SpecifiedTradeAllowanceCharge. Use a permitted code matching the discount, such as 95 for a discount or 100 for a special rebate. Put explanatory text in ram:Reason rather than the code field. Export again and recheck.
