Please help me with this reporting requirement .

There is a report in dashboard under reports category.

Team A will see results where Dept = A, Team B will see results where Dept =B (A and B are part of operator settings)

Team Manager will see results from both Dept A and B, and sometimes they filter data by choosing A or B also.

So now when i give the filter option Team A can change filter setting to Dept B , Team B Can change filter setting to Dept A and view results,

So please let me know how to enable report filtering for selected people ONLY. thank you.
