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.
