kkab tcode

HI,

My functional consultant ran KKAB tcode and generated a report in which planned costs, actual costs etc are the columns.

Now my task is to investigate from which table the data is being retrieved for the column 'actual costs' . For this I searched the prog SAPMSSY0 and its include programs, but I didnt get the result.

Is there any other way to search for this field..

plz suggest me...its very urgent...

Thanks,

Satish.
