AR - GL Integration - Cash account for receipts

Currently, the cash account for an AR receipt is being derived based on the bank account - which in turn is dependent on the payment method. The issue we have is that even if there is a different segment value for one of the accounting segments - as they all belong to one payment method  & bank account - the cash account defaults as the same one

E.g - Segment value1. ABC Bank a/c - XYZ Payment method - cash account is 9999

     - Segment value 2 - ABC Bank a/c - XYZ Payment method - cash account is 9999

In the above example though the segment values are different - the same cash account is being derived as it is derived based on the payment method and the bank account
