We have Micros 3700 and honestly our trainer didn't have all the answers to all the questions we had. On our old system if you hit a dish and the condiments popped up the ones that were already in the dish were programmed in so that when you pressed the button for them the system would exclude them from the dish. Like if the dish already had tomatoes in it and you hit the tomato button it would say "no tomatoes" under the dish. Our programmer just said if we ever didn't want something in the dish we would have to write a message saying "no tomatoes" instead of hitting the button. Is there any way I can program the computer so if you hit an ingredient that's already in a dish it says to exclude it?
