Selling and returning a core product on a stock order
You can enter a return line on a stock order if the customer returns the dirty core at the same time the re-manufactured core product is purchased. If the customer returns the dirty core later, you can edit the sales order to add the return line. If you are unable to edit the sales order, you can enter the dirty core return on another order.
Use these instructions to create a stock order with a re-manufactured core product and a dirty core return.
