I couldn't get the positing reporting structure to work. (My Work Area -> Visualize -> My Positions).
In SAP, the S-S relationships are setup properly. In the admin console, it has similar setup as Org Chart (my reporting structure is shown correctly in Org Chart).
I also checked Area of Responsibility. This is where I get a bit confused. I have set up it correctly for the standard org structure (My Work Area -> Visualize -> My Org Units). Area of Responsiblity is between Org Unit and Position. However, for My Positions, the relationship is S-S. How do I set this up?
