We have developed a working Gateway service in our S4 /HANA backend.
We made a few modifications to this service and re-generated the runtime it without any issues (the service still works as expected).
Suddenly, the buttons under the Service Maintenance are disabled as shown below;
we had tried severally to clear the caches ("/IWBEP/Cache_Cleanup" and "/IWFND/Cache_Cleanup") without success.
Seems like the SEGW may be buggy.
Note: the service still works as expected with the FIORI Apps
Kindly point us in the right direction on how to resolve this issues
