System Aliases definition for Fiori
I see many projects face issues for running Fiori launchpad and Fiori apps because the basic settings were wrong. If basic settings are wrong, you will waste long time for troubleshooting. Do the right thing in the beginning .
One of the setting is the “System Alias” definition. Please compare your settings with this settings.

IMG: Manage SAP System Aliases in the frontend server (Gateway server)
Hub deployment: 2 servers = frontend + backend.
Hub deployment is the recommended option for productive use.
- LOCAL : Set the Local GW on.
- BACK_1 : Specify the TRUSTED RFC destination. Do not set any flag.
- BACK_PGW : This is used for My Inbox(New) and Approve Requests (old) apps. Set the For Local App on. Software version is /IWPGW/BWF
Embedded deployment: (1 single server = frontend components are installed on backend)
Embedded deployment is used often for sandbox test system.
If the landscape is Embedded deployment, everything goes to LOCAL.
Please let me know if this setting is wrong. I always work on hub deployment and do not have enough experience on embedded deployment.
You can define like Hub deployment but RFC destination (SIDCLNT100) points to local.
