In principle, three variants are available for the integration of mobileX-MIP for Field Service, mobileX-CrossMIP and mobileX-Dispatch with SAP S/4HANA “on premise”, according to the migration strategy of companies to S/4HANA:
1. Brownfield approach: the continuation of the previous CS/PM process on the S/4HANA system including own adaptations for this process.
2. Greenfield approach: conversion to the new S/4HANA service process
3. Hybrid approach: a mixture of both variants for e.g. different branches or subsidiaries.
Which of the variants is most suitable depends on how companies want to design the transition to the S/4HANA world for the service or maintenance process in general and for their dispatchers and technicians.
Transfer of existing processes from the ERP
If a company already uses mobileX-Dispatch and mobileX-MIP for Field Service or mobileX-CrossMIP in the ERP environment and does not want to switch to the new processes in S/4Service in the first step, the existing mobileX-Add-On for SAP ERP including all extensions can continue to be used 1:1. No further changes to the mobile client or scheduling are then necessary. SAP will continue to support these processes until at least 2025.
This gives companies sufficient time to switch to S/4HANA, gain experience with the system and the processes and make a gradual transition as described in the “Mixed operation” option.
Greenfield – conversion to the S/4HANA service process
If a company chooses the greenfield approach and also converts its internal processes in the service to the new SAP processes, the integration with mobileX-MIP for Field Service, mobileX-CrossMIP and mobileX-Dispatch can be done out-of-the-box via the new mobileX Add-On for SAP S/4HANA.
Whether adaptations to the mobile client or dispatch can be adopted must be checked in each individual case and, if necessary, adapted to the new processes. This is usually possible for processes that have not undergone any change in the S/4 service (such as large parts of the material process) without any adaptation effort in mobileX-MIP.
The certified mobileX-Add-On for SAP S/4HANA also enables mixed operation of both processes. Companies can use it to integrate both classic CS/PM and new S/4 service orders with mobileX-MIP for Field Service, mobileX-CrossMIP and mobileX-Dispatch. Depending on the scenario, this can be done transparently for technicians and dispatchers on one instance of mobileX-MIP for Field Service, mobileX-CrossMIP and mobileX-Dispatch.
In this way, companies can gain experience with the new process, e.g. in smaller national companies or certain regions, and do not have to convert all systems in a “big bang”.
