Describing Benefits

Objective

After completing this lesson, you will be able to describe benefits of phase model

Benefits of the Phase-Based Process

The comprehensive phase-based process supports you in the maintenance of technical objects. Maintenance requests and orders are processed according to nine phases.

The phase-based maintenance process has been designed to be used within the functional scope of the Reactive Maintenance (4HH) and Proactive Maintenance (4HI) scope items that differs from how the maintenance process had been run before (based on the scope items BH1, BH2 and BJ2). This means that you can only process your maintenance orders according to phases if the scope items Reactive Maintenance and Proactive Maintenance are active or if you have configured the phase model in Customizing the same way as it is delivered for these scope items.

According to this model, all maintenance orders of the Reactive Maintenance and Proactive Maintenance order types are processed with additional planning, approval, preparation, scheduling, and execution steps that are also reflected in additional system statuses.

Processes using the Phase Model

The following processes support the phase model:

  • Reactive Maintenance: The process that involves this order type allows you to perform maintenance of technical objects whenever a breakdown or a failure occurs. This process helps you reduce an asset’s downtime and increase productivity.

  • Proactive Maintenance: The process that involves this order type allows you to prevent the failure or breakdown of an asset by implementing preventive maintenance and using proactive measures. This ensures that the assets are well utilized and are available. It encourages optimal performance of assets and reduces cost by minimizing breakdowns.

  • Improvement Maintenance (4VT): Perform and track work that leads to improvement of assets such as redesign, upgrades etc. - integrated with Project Management (Supports the phase model).

  • Operational and Overhead Maintenance (4WM‏): Record activities such as training, development, documentation, routine work, and so on (Supports the phase model).

Note

Scope Items 4VT and 4WM are only available in SAP S/4HANA Cloud, Public Edition.

Phases and Subphases

Diagram depicting phases and subphases. They are described in the following text.

Phases

All maintenance orders of the Reactive Maintenance and Proactive Maintenance order types are processed with additional planning, approval, preparation, scheduling, and execution steps that are also reflected in additional system statuses.

Phase Control Codes

Phase control codes allow you to control the transition of phases. If you activate a phase control code for a maintenance order for blocking a phase, the system will not allow you to transition to the phase until you deactivate the phase control code. Phase control codes can be activated for order headers and operations.

As of SAP S/4HANA 2023 you can control the validity of phase control codes.

The business or legal requirements might have changed in a way that a previously configured phase control code becomes irrelevant. To depict this, you can determine the validity of a phase control code. You can indicate whether the phase control code is still valid (Valid), will no longer be used in future (Deprecated) or is an invalid entry (No longer valid).
