Since announcing the SAP acquisition of Coresystems FSM in June, Coresystems FSM AG has been hard at work, migrating their applications to the SAP environment.
The mobile applications have been rebranded and uploaded to the Apple and Google Play stores and SAP Marketplace ( Windows Desktop App).
Transition from Coresystems FSM to SAP
Starting with the 7.8.0 release scheduled for late-January 2019, the mobile apps will no longer be updated and will be removed from the stores by 22 March 2019. Existing customers should migrate to the SAP FSM apps.
An In-App popup will appear in the iOS and Android 7.8.0 apps, asking users to download the new application.
For Windows, since there is no app store listing, companies wishing to distribute new versions of the EXE to their technicians should download it from the SAP page.
