Processing Returns with Point of Sale
During processing, a credit memo is created to reverse the invoice, and a debit memo is created to reverse the payments. To process a a return through the Point of Sale (POS) feature, perform these steps:
- Find and reverse the original order
- Verify and finalize the information
Note:  These steps 
 assume that you are logged into a cash drawer and at least one Point of 
 Sale material order entry is already in the system. The customer now wants 
 to return the original purchase. For more information on logging into 
 cash drawers or entering orders in POS, see Processing 
 Orders with Point of Sale.
