Imran just it very simple
First create a measuring point in IK01 with characteristics HR with target value. After that you create initial measuring document in IK11.
Secondly Create a single cycle plan in IP41 put your cycle/unit (say 8/Day HR) & below you can see the counter from your initial document no. Here you must keep in mind configuring the Factory calendar as per your business working days & hours. Now choose the maintenance plan scheduling parameters keeping call horizon and scheduling parameters even you can take the completion requirements too on the right side of this you can take time & factory calendar save it & schedule now through IP10 for the first time a reference object ( Notification/Order as per req.) will be called up.
hope it have given you some more clarity.
