I can remove/change table by click Change Table Button on the top left of the screen and click X on the top right to remove the table.
But I’m wondering if I can do it thru Rule/Action.
I want to create pre order ticket on main Restaurant screen which use Table but after convert those ticket to active ticket (now will be in takeout/delivery screen which use customer entity), I want it to become available for next pre order one so, I dont have to have a lot of pre order button on screen.
So why are you creating Pre Order tickets on Tables? Maybe explain your process we can help you design it and get it working? I can usually help someone better if I understand the flow your trying to achieve.
