Thanks Kamal for you input...!!
But i am not through with the issue.
Still i am getting the current month actual cost only.
as per your point i did change the cut-off period to 16,2015.( KKA0)..is this the only setting i need to do?
please correct me if i have done RA and the settlement for the previous period(01) so in current month (2nd month)expecting the cumulative actual cost including the previous month cost..is it correct?
Please do explain me the correct way of doing if i am not on the right path.
