We are in a process of checking plan vs actual cost cost-element wise.
I have gone through a useful thred that is very similar to my requirement -http://scn.sap.com/thread/1740436
Here it is mentioned to use user exit us250 in RGGBR000 but when I look into the program , not able to find that specific user exit .
Although User exit u100 is there, but not meeting my requirement.
Can some one please guide me how to activate that user exit in order to put a check my budget cost that is maintained in KP06 .
