Requirement: If a customer goes to a store to exchange/return a product after a sale is made e.g., item A $20 item B $30. Returned item A and item B and bought new item C at $ 25 so a net credit of $ 25 should be given back to the customer payment card.
Currently this is coming from the stores as one message and would like to process sales as well as returns in one order how to accomplish this? We don't want to split the order for sales and returns as it will generate separate billing documents hence two transactions will be in the customer payment card statement, we would like to keep it to one billing doc. Please advice ASAP. Thanks in Advance.
