- For embedded scenario (Gateway + SolMan in same system), 'Local App' needs to be checked in System Alias Configuration.
- Can you check if you can use the service from the browser? atleast the metadata? If you do not know the URI, go to /IWFND/MAINT_SERVICE, select your service. There should be a button to see the service document. Also in the same Tcode on right botton, you can see the system alias used by this service. Is it the same as LOCAL_SM?
