Matrix Structure

Hi Experts,

I have created matrix structure where 1 person is reporting to 3 different Org Units.But i have maintained reporting percentage of employee to different Org units.For example,Person X reporting % to HR Org unit is 50% and to IT Org unit its 30%.Now i want this percentage also to be displayed in matrix view which is not happening.I got an option in standard,ie view-----> Percent on.But percent on is grayed out. Pls help as of how to view the reporting %.

I have assigned weighting percentages in pp01.

Regards
