It would be useful if you could replicate the PO prepayment functionality and apply similar functionality on the sales order side. We frequently have requests from clients to be able to create payments in advance from customers and link them to a SO. I know it is possible to create a prepayment journal and link that to the sales order using existing functionality but the problem is there are limitations. These are as follows:-
1) You can't generate an invoice off the back of the prepayment
2) It is not easy to see what prepayments you have generated in the system with remaining balances.
3). It would be a simpler process if you could generate the prepayment directly from the SO, similar to the PO prepayment function.
