Could anyone clarify the best practice for refunding a customer under the following circumstances:
1. We created a sales order for several items
2. We billed everything with a Cash Sale to record receiving the funds
3. All but one item was shipped out, one was backordered
4. After 2 months of not getting stock for the backordered item, the customer wants to cancel it.
5. If I create a Cash Refund from the Cash Sale, I am forced to enter the inventory detail of the item being refunded, but it never shipped out in the first place.
How would you recommend I complete this refund without affecting inventory?
