8.4 Preventative Maintenance
There have been significant performance improvements in the scheduling of maintenance plans and the deadline monitoring process.
8.4.1 Scheduling of Maintenance Plans
The transactions and execution of the process remains the same, but the time to schedule and react is significantly improved. The following SAP Fiori apps are provided in the EAM Maintenance Plan app group (see Figure 8.27).

Create Maintenance Plan
You generate maintenance plans to ensure equipment is periodically inspected. The maintenance plan is used to plan when and what is expected. The Create Maintenance Plan app in SAP S/4HANA (see Figure 8.28) is similar to Transaction IP41 in SAP Business Suite.
Figure 8.28 Create Maintenance Plan Initial Screen
When creating a maintenance plan, the scheduling data is entered in the Planning Data tab, as shown in Figure 8.29.

SAP S/4HANA also allows for the mass scheduling of maintenance plans. This functionality mimics the traditional Business Suite functionality in Transaction IP30. This functionality allows for jobs to be scheduled and sorted based on maintenance status and deadline dates.
In addition, SAP Fiori apps exist for Resource Scheduling for Maintenance which allows maintenance planners to monitor the status of work centers and see the existing maintenance orders or schedule needed maintenance. Along with this app, is a graphical representation of the maintenance scheduling via interactive Gantt charts with drag and drop capabilities enabled via the Maintenance Scheduling Board SAP Fiori app.
Changing and Displaying Existing Maintenance Plans
There are also SAP Fiori apps for Changing and Displaying existing maintenance plans (Figure 8.30).

Scheduling Maintenance Plans
Scheduling maintenance plans hasn’t changed via the GUI in SAP S/4HANA. Transaction code IP10 is used to generate the maintenance objects (see Figure 8.31).

8.4.2 Maintenance Plans with Item Lists
This functionality enables the user to build a personalized list of maintenance plans and corresponding item lists that allow for individual processing and mass processing with a combined list view of maintenance plans and items.
The Maintenance Plan Item apps shown in Figure 8.33 are provided.
Figure 8.33 Maintenance Plan Item App Suite
Display Maintenance Item
Maintenance plans can be created with or without maintenance items. The maintenance items act as a task list for tasks that need to be performed for a technical object (Figure 8.34). The management of maintenance items can be performed via SAP Fiori apps that replicate functionality from Transaction IP04 in SAP Business Suite.
Figure 8.34 Display Maintenance Item App
Included in the Maintenance Plan Item app suite is the Manage Maintenance Plan and Item List app (Figure 8.35). This SAP Fiori app is used by maintenance planners to help monitor all of the maintenance plans and items lists and to make mass updates.

Measurement Documents
SAP measurement documents are used to capture actual measurement data from a specific piece of equipment. The measurement data acts as a reading from the equipment that is used in maintenance processing to determine if action is needed. Often, these measurements are automatically interfaced directly from software on the machines being measured. These EAM Measurement Document apps are shown in Figure 8.36.
Figure 8.36 Measurement Document App Suite
The Create Measurement Document app can be used to capture the results data. This SAP Fiori app mimics Transaction IK11 in SAP Business Suite. The initial screen and the detail screen are shown in Figure 8.37 and Figure 8.38, respectively.
