I've followed the set up for creating vouchers, including serial numbers, with zero value, to be filled in at the P.O.S.
If a customer returns an item I want to issue credit for instead of a refund, I have tried scanning the return, then issuing payment for it in the form of a credit note, by entering the credit item lookup code, this then asks for the serial number, the option to lookup is grayed out, but if I type in one of the numbers I know exists, I get a message saying this voucher hasn't been sold yet.....can anyone tell me what step I am missing on this ?
Thanks, marwat.
