How to settle deduction in Trade Management with RMA Settlement Method.

 Scenario:
-------------

Created a Sales Order 500000001 for Item 00000001 with Qty as 10 and Unit Price as 100.

Sales Order is ship confirmed & closed, Invoice (10360) is created in AR for 1000.
Customer has Paid 800 dollars & a Receipt is created as R10360.
As part of the cash application process a deduction is created for 200 & a claim number us

generated as DED10360.
As part of the claim settlement process, RMA is chosen as the settlement method.
Once approval is done, the RMA Order is created in OM.
However I am unable to proceed further. When I try to book the RMA Order I get the below error.
