Getting Actual and Planned Cost from WBS/Project

Hi Gurus,

We are trying to develop a report to display actual and planned values of multiple WBS with respect to multiple WBS/Project number.

-We are pulling the Actual cost values from table COEP which match with CJI3 Actual values.

-We are pulling the planned cost from table COSP which gives only planned cost on network (Primary posting values). and its doesnt show planned cost for WBS (Secondary Cost).

-In COSS we are getting actual cost for WBS only.

Could you please suggest us table which can provide actual and planned cost for WBS/Network.

Thanks

SK
