We sell a lot of special work order items. Our usual order flow is Sales Order > Transformed to cash sale > Build work order > Item fulfilment. We're having an issue with unwanted assemblies being returned onto stock in error. We think that Cash Refunds are returning assemblies to stock, even when the original work order is not built. I know there's an option on return item receipts to decide whether an item is returned to stock, but can't find similar for Cash Refunds. Does anyone know of any fields or settings which might affect this?

The refund has to have only non inventory items on it or be created from a return authorization/credit memo

Or set the Cash Refund quantity to 0, if you don't want it to restock.
