Help about setting problem

[u882146]

In my school, Grade1&2 both have exercise class, health class and physical class, three kinds of calss.
The rule is that each class needs to be separated in different days. Each class has its own teacher and specific place. So exercise class, health class and physical class need to link with "Space" of FET program due to limited capability of playground. So we have to control total students in the same class time at playground, exercise room. How can I do settings in the above situation? Hope you can help me! Thanks a lot!

I am not sure if i understood correct. But i think you can use time constraint -> activities -> a set of activities is not overlapping.

If that doesn't help. Please explain a bit more detailed. maybe attach you last timetable and explain more detailed what is allowed and what not.

English is not my mother language. I try to describe my question in detail,

I have A B C, three kinds of classes. Every two of them are not allowed to schedule on the same day.
For example, if A is arranged on Monday, then B or C is forbidden on Monday.


How can I do settings?

Maybe use constraint min 1 days between activities, or constrain the activities to rooms and different buildings and use max 0 building changes.

I corrected a mistake in my previous post, it is min 1 days between activities.
