Can 2 teachers teach the same course at the same time but in different subjects?

[infoo_]

Hello

I have two teachers A and B, and these teachers must teach at the same time in a divided course (Teacher A teaches Arts on course 3B, and Teacher B teaches Music on course 3B, for example).

However, the information of available time they gave me is different for both (which is normal). Is there a constraint that fits, for a course and subject, the "intersection" of both available time to teach in the same hour?

I thought of creating a Teacher called "Teacher A/Teacher B" and a Subject called "Arts/Music" and "Teacher A/Teacher B" available time's is the intersection of Teacher A and Teacher B available times. Also, of course two teachers: a "Teacher A" and a "Teacher B" are created because they teach other subjects separately.

However this intersection is calculated by hand, and, while there aren't many subjects where the course needs to be split, I feel like there's a better way to solve this problem.

I am starting to use FET. Is there a solution that doesn't use divided courses? Perhaps a constraint?

I am using Official mode and Version: 6.8.0 (January 2023).

Thanks in advance

Hello,

It seems very easy, constraint activities same starting time (day+hour)?
