1. System Alias for SAP-Fiori (Front-End) System: 'Local'
   
   
   
   • Local System alias is required to refer objects of same system

   • 
   
   
   • Here check boxes 'Local GW' & 'For Local App' should be checked.
   
   
   
   


2. System Alias for SAP-ECC (Back-End) System
   
   
   
   • This system alias is required to refer objects of for SAP-ECC (Back-End) System
   
   
   • Below settings needs to be configured in 'Manage SAP System Aliases' window
   
   
   • 
   
   
   • Enter RFC-Destination and check boxes 'Local GW' & 'For Local App' should be un-checked.
   
   
   • RFC-Destination should have enabled 'Current-User' logon settings
