Z report for Process Order

Dear All,

I`m not able to find out the tables where data for Planned material cost,Planned Quantity, Planned overheads are stored for Process Order.

Below are the tables I tried to get the values but all of them has one or the other problem:

I have used COEP - but system is giving time out,

I have used S027 - but it is showing wrong values.

PLAF is also used but it is asking for Planned order number.

AFPO- In this i`m not getting the planned quantity for raw materials.....

I have also tried BOM tables STKO and STPO but it is giving rounding off problem.....

Please guide me how to achieve it...

Regards
