Does it show correct when go to settle screen?
At a guess it’s updated but not refreshed on screen as within order selected mode maybe…
Had similar with my custom discounts system, refresh ticket action probably help.
Although a simple 10% like that you could just do a rate based calculation rather than automating updating a fixed type calc.
i use quick settlement buttons for this part of the my setup, but if i print the bill it still shows the error
yeah, my original setup i was using a direct price adjustment and found it wasn’t working correctly with the takeaway price definition at the same time, resulting in customers being accidentally overcharged.
I guess i could strip it back and use an order tag on each item that i update the price on, which should respect the price definitions.
