RE: how can we prevent $0 sales?
That's right. The second way is the one i wanted.
I set the lower bound value at 0.01, but it is sold equally at POS as $0.
I think, the lower bound function doesn't seem to work. I don't get errors like warning 903.
Is it an error that occurs when the cashier changes to $0?
Can i see the above error in POS when i change $0 in RMS, not a cashier?
Thank you very much for your kind reply.!!!
