Thank-you team for this tutorial, I have followed this tutorial to the detail however and am particularly concerned when the waiters want to add more items on a previous (Submitted)printed bill
Waiters have a way to reprint the same bill. Initially, when the waiters print the bill, the print bill button “grey out” meaning for you to use it again you have to unlock the ticket. So I disabled unlock the ticket button. What happens is the waiter will add an item on the said ticket and cancel the same item before submitting, this makes the print bill button to appear highlighted hence he can now reprint the same bill.
Please let know-how to restrict adding of items on submitted bills
