Hi Atif,
you dont want to control PR, PO, GR or IR??? you have to control among one of these. For making this you can use value type ( in OF36 ).for example, if you dont want to control PO you can select statistically.
If you want to control using fund center, you must set up derivation rules in FMDERIVE. Derivation rules that you will define can change according to your process. Which level do you want to make control? Only fund center?
