Assignment of tasks to different roles.

I 'm doing a process where they act three roles: employee , assistant manager and manager. As I can do to make the employee only show you the tasks and also with the assistant manager and manager .

If anyone can help me thank you very much .

Could you please elaborate, i didn’t understand your question.

I have 3 lanes each one assigned to a actor, as I do to make the actor of the first lane does not appear you the tasks of the second lane and as I do to the second lan does not appear you the activities of the third path?

Are each actor in separate groups?

No, They are related to the same group

Separate each actor in different groups and you’ll notice that no other users receives the task besides those included in the group
