Evaluation path for team calender in MSS

Hi Experts,

I need to configure an evaluation path as follows.

1. A manager M1 belongs to org unit O1. He manages Org unit O2.

2. Org unit O2 reports to O1. similarly O3 also reports to O1.

3. Now I need to develop a evaluation path in which, M1 should have visibility to all employees from both O2 and O3 in his MSS..

I have tried out many combinations with A002 and B002 relationships. but it not working.

So could you help me to build this evaluation path.

Thanks

Sameer
