Use return credit on a later purchase

Follow these steps

1. Open the original eligible sale and record a return.
2. Choose a reusable return-credit slip where the return workflow offers one.
3. Keep the slip code and remaining balance accessible to the appropriate customer.
4. On the later replacement purchase, open checkout and enter the return-credit slip.
5. Apply no more than its available balance and settle any extra amount.
6. Finish the sale and check that both transactions remain linked.
