return adjustment without item

[wperng]

Hi,
 
I would like to use return without returning any items, just return
adjustment.  But I have problem to have the payment to be refunded to credit
card automatically after the return adjustment item is created.
 
Can anyone please tell me what should be the next step after the "Accept
Return" button in the Order Items page is clicked, if I want the adjustment
to be refunded to credit card automatically ?
 
Thanks
