SAP delivered phase & sub-phase maintenance model called “reactive maintenance” in SAP S/4HANA 2021 release. It was released earlier in cloud version. Best practice code for the same in “4HH”. These phases or sub-phases cannot be modified! Activating the phase model for an order type has no effect on already created orders of the same type.

These phases can be compared to statuses which permits or prohibits the continuation of business process. This is done using “Phase Control Code” which is configurable & allows transition of phases.

With the phase model:

There are other new phase based processes like proactive maintenance, improvement maintenance, operational & overhead maintenance. I will try to cover these topics in the separate blogs.
