I need to create report to pull performance rating given by manager. Right now i am using : Workforce Management - Performance Rating Real Time subject area. I need to get email id also for an employee so had added second subject area : Workforce Management - Person Real Time. But once i have added second subject area and checking results then few columns like Position Name , Job code , Department Name etc are coming blank. I have checked the dimensionality box in advanced tab also.

Please someone advice whether am i missing something.
