FX-SCH-A-000623: Use an allowed line discount reason code

In short

Error: fails the selected checks.

FX-SCH-A-000623 means your line discount reason code (BT-140) is not on the allowed list. Use a matching UNTDID 5189 code, such as 95 for a discount, or remove the code and give the reason as text.

What it means

This checks ram:ReasonCode in a line-level ram:SpecifiedTradeAllowanceCharge where ram:ChargeIndicator/udt:Indicator has the value false. This is a line discount (BG-27), with reason text BT-139 and reason code BT-140. An empty code passes this check; a non-empty code must be listed.

Why it matters

A reason code identifies the type of discount using an agreed list. A written explanation belongs in the separate reason text field.

How to fix it

Replace ram:ReasonCode with the UNTDID 5189 code that matches your discount. Alternatively, remove ram:ReasonCode and put a short explanation, such as "Volume discount", in ram:Reason (BT-139). Do not put free text in the code element. Export the corrected file and recheck it.
