Rescheduling a Maintenance Plan (SAP Library - Test Equipment Management (QM-IT))

Rescheduling a Maintenance Plan

Prerequisites

If you want to reschedule a maintenance plan, different prerequisites apply according to the types of maintenance plan:

Time-Based Maintenance Plan

To reschedule a time-based maintenance plan using the scheduling function, you must first confirm the maintenance plans called up, for which an order has already been created. After this confirmation, the system performs scheduling automatically.

Performance-Based Maintenance Plan and Multiple Counter Plan

Before you reschedule a performance-based maintenance plan, you should ensure that the overall counter reading of the counter which is assigned to the maintenance plan is current. If you reschedule a performance-based maintenance plan, the system assumes that the counter readings are current and calculates the planned dates accordingly. Before the actual scheduling, you must confirm the maintenance plans called up, for which an order has already been provided. After this confirmation, the system performs scheduling automatically.

Procedure

Choose Logistics ® Quality management ® Test equipment management ® Calibration planning ® Maintenance planning ® Scheduling.

You reach the initial screen for scheduling a maintenance plan.

Enter the number of the maintenance plan that you want to reschedule and choose Enter.

You reach the Schedule Maintenance Plan screen.

To reschedule the maintenance plan, choose Edit ® Confirm.

Further editing depends on the type of maintenance plan. Choose the procedure suitable for you from the following list and proceed accordingly.

Time-Based Maintenance Plans

The system highlights the field CompConfDate and proposes a completion confirmation date.

Change this date if necessary and confirm it by choosing Enter.

The system then performs the following functions automatically:

It confirms the last due date with the status Called, not yet confirmed as Called, completed.
It recalculates all subsequent calls based on the scheduling parameters. For this, it includes shift factors, new maintenance packages and so on.
It ensures that there is at least one maintenance call with the status On hold.

Performance-Based Maintenance Plans

The system shows the field Completion confirmation highlighted and ready for input.

Enter the counter reading and confirm it by choosing Enter.

The system automatically calculates the task list and the maintenance call date based on the maintenance packages, scheduling parameters, estimated annual performance and the counter reading at the start of the cycle. It then displays the following: counter unit, counter reading at the start of the cycle, counter reading for the completion confirmation date and the next planned counter reading for the next due date.

Multiple Counter Plans

The system uses the current date as the completion confirmation date and automatically calculates the next planned date based on the maintenance cycles, scheduling parameters, estimated annual performance and the last counter readings. Then it displays the following: counter reading units, last counter readings, next planned counter readings and planned dates.

The planned date for which an order is created depends on the link type in the multiple counter plan. For an OR link, the system selects the earliest planned date, whereas for an AND link, it selects the latest.

You can cancel scheduling. Return to the Schedule Maintenance Plan screen and choose Edit ® Cancel scheduling.

Save the maintenance plan.

For more information about working with maintenance plans (for example, automatic scheduling), see PM – Maintenance Planning.

Result

The maintenance plan now contains maintenance calls which the system releases automatically for the due date. However, you can also release the calls manually.

When a maintenance plan is released, the system automatically generates an order, and when the order is released, it generates an inspection lot.
