Budget,Actual and committment costs..

I am working on a z report since long time, My requirement is to get budget, actual cost, committment cost, advances in the Z report. I provided data to Abaper with OBJNR to BPGE table and retrieve the data from WTGES for Budget.

Now I need the same for Actual cost, committment cost and Advances. Can any one please help me the logic/tables to retrieve the above said Actual cost, committment cost and advances.

Thank you
