Over return

HI,

We have a scenario where we need to over return the quantity. We are on 12.1.3

Sales order# 123

order quantity : 5

shipped qty :5

invoiced qty: 5

Return order# 456

RMA qty line 1: 5 (this will be with receipt and credit WF)

Return order# 789

RMA qty line 1: 2 (this will be a Credit only WF)

both RMA lines from 456 & 789 should refer to the original sales order# 123. However while booking the return order# 789 we are getting the error ' Quantity cannot be greater than original ordered quantity'. I cannot skip the original

sales order reference as it is needed for our business process. We dont want to adjust or do anything in AR side, so the idea was to create an RMA with credit only WF by referring to the original sales order and let it go to AR for application.
