SLA- AR - Credit Memo - revenue accpunt based on credit memo reason defined in a lookup

All,

Business have a requirement that revenue journal accounting line for a credit memo should be populated with account segment based on the credit memo reason that a user selects while creating that credit memo.

I created an ADR and assigned a mapping set to that ADR. assigned ADR to JLD, assigned that to JLT, assigned that to ADD and validated it. it gets validated successfully.

I performed below steps -

1. created a credit memo with a credit reason.

2. run accounting.

but JE line still shows the natural account same as credit memo distribution GL account. it should be the one assigned to the credit reason in mapping set.
