Introducing Overhead Maintenance (4WM)

After a maintenance request is approved, we are in Planning phase of this process. The approved Maintenance Request will be called Maintenance Notification. This process step shows how to convert a maintenance notification into a maintenance order and, provides details about planning the resources for the order.

Order processing helps you to plan maintenance tasks in greater detail. You decide the tasks to be performed and what components (materials) are needed, and so on.

After you have planned resources for the maintenance order, it can be submitted for approval to the supervisor. This will set the status of the maintenance order to Ready to Prepare subphase.

This process step shows you how to approve a maintenance order from My Inbox (F0862) app.

We are in Ready to Prepare subphase. In this process step, you can review a list of approved maintenance orders and release them for Preparation phase.

The maintenance order is in Preparation phase now. Maintenance Backlog Overview screen will allow you to view various cards. You can check Maintenance Backlog Card which shows backlog of maintenance orders based on phase or buckets.

This process step shows you how to assign purchase requisitions to a source of supply and to convert assigned source purchase requisitions to purchase orders.

Here you post the goods receipt for the purchase order.

You are now in Execution phase of the process. Here you post the goods issue from storage location.

Once Preparation is done and backlog is reviewed, the order can be set for Ready to Schedule to start Scheduling phase.

In this step, you can schedule the order operations and set the operations ready for execution.

In Execution phase, technician will execute Pre and Main operations.

After execution of Pre and Main work by the Technician, the Maintenance Supervisor will review the work and change the status from Main Work Completed to Post Execution phase.

In this activity, you report the performed services in the service entry sheet.

In this process step, the technician will execute post operations activities (if any) and also update the malfunction details and failure data.

Maintenance planner can review the cost of maintenance orders.

The maintenance notification is completed and the maintenance order is technically completed after the required maintenance work has been performed.

The technical completion reduces all the purchase requisitions, open reservations, and capacities still outstanding for the maintenance order.

Nevertheless, the order can continue to receive costs, for example, through invoice receipts for delivered and used materials. However it is blocked for all changes in the processing.

The order settlement transfers the costs incurred that were temporarily collected for the maintenance order, to the recipient, for example, to the cost center for the maintained object. This process step shows you how to technically complete a maintenance order.

In this process step you create the invoice with reference to the purchase order.

In this process step you release a blocked supplier invoice.
