How do we issue credit card refund on Micros 3700? I tried to method where we press VOID, then the AMOUNT, then the NON-REV key, then swipe the card as usual, but I am getting an error message something like "not allowed with line item detail." This void/non-rev method used to work, but now all of the sudden, I am getting this new error. Seems like our POS has a mind of it's own and changes it whenever it wants.
