Cost plannig & Activity Confirmation

Hi Experts,

I want to do the cost planing at activity level so for this i have create one sub activity with selecting of control key PS03 which having select indicator Gen. Cost ACt. to allowed to doing cost planning. But I am doing confirmation on main activity level hense when i have seen the report in CNE5 result get display like Cost planning i can see at Subactivity level & confirm progress i can see at main activity level.

So is it possible to do it at main activity level. (Cost planning & Progress Confirmation)
