I set the maximum value to 3 and it worked

thank you

After adding DT to these activities, will these activities not conflict in time, since DT is the same and the same teacher should not be able to teach more than one class at the same time?

How to associate the virtual teacher DT with such activities?

I have a requirement: for example, there are five days, each lasting two hours. Teachers' classes can be combined, but a particular teacher's class cannot exceed three days. How can this be implemented? FETs generally don't allow repeated classes. If I change the teacher names to Zhang San 1 and Zhang San 2, how can I ensure that the maximum number of days for a teacher with Zhang San in their name cannot exceed three? Alternatively, can You add a constraint that limits the maximum number of days a series of activities can be within a week?

thank you !

Is there a way to combine these classes into one activity? For example, it would be more convenient to combine the math classes of classes 5 and 6 into one activity.

    Can we add two constraints: a priority time period for a group of activities and an exclusion time period for a group of activities?
    In our school, English and math are taught in Class A and Class B based on the natural class. That is, other subjects are taught in the natural class, and when it comes to English and math, they are divided into Class A and Class B. Due to the shortage of teachers and considerations for teaching effectiveness, there is a math teacher who teaches Class A of students 5, 6, 7, and 8, and a partner teacher who teaches Class B of students 5, 6, 7, and 8. During class time, Class A of students 5 and 6 attends the Class 5 classroom, and Class B of students 5 and 6 attends the Class 6 classroom. When scheduling, the math classes of classes 5 and 6 are taught at the same time. Sometimes, this teacher would like to give priority to teaching in the 2nd and 3rd time periods, and does not want to teach in the 1st time period. Is there any good way to solve this problem? If so, please let me know. Or, as the title says, can we add two constraints to solve this problem?
