This is easy enough to recreate (at least for me)

If I get a sale and the shippng is incorrect I cannot issue a partial refund from the E-Commerce Control Panel. I have to issue a complete refund the go to the ePay gateway and redo the proper charge.

Here is the transaction history from the control panel:

Payment History

Transaction ID Amount Action Status Reason Date Gateway Code Gateway Response
76078674 $17.95 Sale Approved 9/2/08 6:58 AM 00000 AP
$4.80 Refund Error Shipping refund 9/3/08 7:41 AM 00071 Transaction out of balance.
$4.80 Refund Error Shipping Refund 9/3/08 7:45 AM 00071 Transaction out of balance.
76262367 $17.95 Refund Approved Shipping Refund 9/3/08 7:48 AM 00000 Approved

I have logged this with our DEV team however we do not have an ETA as to when this will be fixed. You should be able to issue partial refunds by logging into the ePay terminal and issuing the refund there for the time being.

Any update on this? I'm having a similar problem. We have some transactions that have already been charged but we need to refund part of the amount. We do have a workaround, using the payment gateway (not ePay but same idea), but it's a lot cleaner from an audit perspective when everything is done from the e-commerce control panel.

When we enter a refund amount and reason code, we get this response from the gateway:

(code) 54 (response) The referenced transaction does not meet the criteria for issuing a credit.

It looks like the original transaction ID could be missing when it sends the refund request.

We don't have an ETA for a fix for this currently.
