Allowing Customers to Field Scrap

SOLVED

What is the most efficient way you have found to process a field scrap?  There are instances when it is not cost effective to have a customer return a damaged item so we allow them to keep the item (field scrap it).  Right now we create an RMA to issue the customer a refund and then we issue the item out of inventory to our scrap expense account.  But is there a better way to do this?  I know there is a scrap option in the RMA module but this puts the scrap item to a balance sheet account (since we also have scrapped items physically here) and we don't want a field scrap to hit the balance sheet.  We would like to try to avoid the item going back into our inventory.  Would the best way to handle this be to simply issue a credit memo to the customer without using the part number and instead just hitting the scrap expense account?
