Credit/Rebill on same vendor invoice

​@ceannoglesby 

We have different types of RMA to execute as per the process.https://www.youtube.com/watch?v=7QJ69xEY-sc

1. Return with replacement
2. Return for credit

This is not on a sales side, this is on a purchase order.

Hello,

Was the incorrect Bill already paid?

1. Reverse the original bill that was linked to your PO/PO Receipt. Release the debit memo created by Acumatica.
2. Create a new Bill of the correct quantity and cost, and link it to the same PO/PO Receipt. 
3. If the Bill in Step 1 was already paid, apply the Debit Adjustment created in step 1 to the new Bill created in step 2 in Payables - Checks & Payments screen. I assume the new bill is lower than the original incorrect bill - so I expect you will end with a net credit on the Vendor’s account (a debit memo that lowers the amount that is owed to the vendor). The remaining debit memo balance may be applied to your next bill from the vendor.
4. If the incorrect Bill was not yet paid, then it has been fully reversed with the Debit created in Step 1. Pay the new bill created in step 2.

Yes, the bill has been paid.  I have a new invocie that contains both a credit and a charge.  Are you saying we will have to enter this one invoice as both an invoice and a debit adjustment?

The vendor calls it a Pricing CR/Rebill, several suppliers do this.
