    I. Pre-requisites:

    •  Equipment master, with measuring point, defined as counter.

    •  Cycle sets as per requirement.

    II. Measuring Point:

    Please ensure filling-up of Annual Estimate tab. This will enable the system to calculate the

    III. Cycle Set creation:

    T.Code: IP11Z

    Note: The cycle set may be created with different cycles, pertaining to specific equipment /

    vehicle.For example, above cycles are suitable for utility equipment like compressors or generators,

    since we use unit of measurement as operating hours.

    By keeping the cycle text as the type of inspection, easy understanding of the cycle is possible.

    The required logic (OR/AND) can be determined while creating maintenance plan.

    IV. Maintenance Plan creation:

    T.Code: IP43

    The required cycle set is selected in the initial screen and execution brings all the selected sets

    in the maintenance plan header.

    Please note how ‘Cycle Set Seq’ (1st row of header) is numbered.

     As can be seen, each pair (4 month OR 250 Hours) is marked as single number. This number

    is used in the item screen, as seen below.

    Note: Each cycle may contain counters of different dimension also. Eg. Nos and hours can be

    used in case of aircraft-No. of landings and flying hours.

    In the above plan, the vehicle mentioned has to under-go all the above 4 cycles in sequence.

    Hence 4 line items are created with the same equipment, but with different Cycle Set Seq, as

    seen above.Different task lists, as per frequency can be attached to respective line items, since strategy

    cannot be used here.

    Note: 1. As illustrated above, it should be noted that the start date is in header level, and

    hence applicable for all items of the plan.

    2. As the equipment is assigned, the respective counter number is automatically picked-up

    at header level, as shown below.
