A teacher on a given day should only go to one branch.

I have a school with three branches. Is it possible to create a constraint so that when a teacher goes to one of the three branches, they don't have to do anything else? For example, three hours in branch A and nothing else

I think the new constraint teachers max activity tags per day introduced in the current stable version FET-6.25.0 just released 2 days ago is exactly what you need: add tags AT1..AT4 (AT4 to the rest of activities), and max 1 per day from these 4 tags.

Please let me know if this solves your problem.

I solved the problem in a while thanks to your support. Thank you!
