Dear Anagha
Indirect Activity Allocation will allocate Activity quantity and the value associated to it. For example Power Cost center you can plan Cost through KP06 and Quantities through KP26. But for production cost centers you do only kp26 i.e. quantity planning in required quantity. Please keep in mind while planning at Power CC you have to use Activity of Activity category '2' or '3' only depending upon your requirement, and for production CC Act type category'1'.
Run Indirect Activity allocation cycle. Then do the KSPI. for power cost center. It will give you desired results. i.e. If you check Cost center report now on the production cost centers Cost and activity quantity both are available. Do KSPI for production cost centers and enjoy.
