Query regarding Tcode PA30(HR)

Hi

When I run the transaction PA30 and I open the Organizational Assignment , all the data is being displayed.I want to add the field "Controlling Area" to the screen.

So , I open "Free Search" on the left hand side and then open the Organizational Assignment.There , when we drag and drop the "Controlling Area" field , that should be added to the screen.But it is not getting added to the screen.

Can anyone tell me how this can be done?

Reward points will definitely be given.

Thanking you

Regards

Chandrika.
