OTBI Report - Count of Terminated Employees By Manager 1, 2 and 3

Summary

We need a summary and detail report that gives count of terminated employees by manager hierarchy.

Content

I am using Workforce Management - Worker Assignment Event Real Time SA.

When I choose Manager 1 and filter it @ Top Manager level I don't get any record but when I remove Manager 1 and remove the Top Manager filter I can see all the terminated employees.

Which SA has info about terminated employee along with its Manager hierarchy.
