How to prohibit making an employee who is on vacation responsible for a task?

Question

Bitrix24

I tried to make a robot that changes the responsible person, everything works, but only if I set the task myself.
Support replied that the robot will work, provided that the task is created for the project (for example, Tasks-IT).
Therefore, I need to at least forbid making an employee on vacation responsible.

UPD:
Entering a vacation into an absence schedule does not prevent the task from being set. Just when choosing such an employee, next to him there will be an inscription that he is on vacation (as experience shows, this does not prevent anyone from setting a task)

Answer 1

You need to use the "Absence Schedule" (see the section in the search for B24 itself).
