Hi Erin,

I believe you need to use the Return order types (RC, RM, RR) depending on how you need to disposition the return (simple credit or replacement).  This handles the credit and subsequent replacement shipment (if needed).

Here’s the help files on the Predefined Sales Order Types

I hope this helps,

Eric

We can reverse the Inventory by placing return orders in Acumatica. The below steps may help you.

1. Create a Return type of order ex: (RC type - RMA behavior) 
2. Create Receipt for this order (From Actions) 
3. It will create shipment type as a “Receipt” and then click on Update IN (It will reverse the Inventory)
4. Prepare an invoice and then will create a “Credit Memo” document. 
5. If Aleady payment is collected for the actual order, we need to create a “Customer Refund” in the Payments and Applications screen for the actual payment.
6. Finally, apply the below documents to the Actual Payment and release. Payment and Invoice will be closed.
   1. Credit Memo
   2. Actual order Invoice

hello, guys,
in my point of view, how about we vote for Acumatica to release a real cancellation function to make work easier.
