In the normal mode of the portal, if an employee of one department tries to assign a task to an employee of another unit, then there will be no problems.
Suppose an employee from the Moscow branch sets a task for an employee from the Novosibirsk branch.
The task is set, despite the fact that the production director belongs to another division.
Using the module "Check of responsible person by structure" you can control the assignment of tasks. After installing the solution, when an employee from one department tries to assign a task to the employee of another unit, the task will be returned to the creator, it means, that he will be appointed as a responsible person in the assigned task.
This logic does not allow you to set tasks for your leader or colleagues from neighboring units.
1. Download the solution on the Marketplace, specify the path for installation.
2. In the administrative part of Bitrix, click Install Updates, and then click Install.
3. After installation, the module does not require any additional settings. Now, when an employee from one department tries to assign a task to an employee of another unit, the task will be returned to the creator.
