Hello Chidambareswara,
As asked by Maria, if you are intending to have Operation Level Costs, then your SAP versions should be EHP5 or above. Here yu need to activate Business function LOG_EAM_OLC. (Related Business function LOG_EAM_OLC2 in EHP6). Contact your BASIS group.
Also Go through these links:

Good luck
