Workflow Organization structure

Dears

Good Day 😊

i have some conflicts in the workflow organization structure as a beginner in SAP workflow

If i have ORG unit has 2 positions

* position checked as department manger

* position for an employee (not manger)

if i select this ORG unit in a task as agent

How can control that all tasks of second position report to his manager only .

Thanks and Best Regards .
