The ABAP front-end server contains the central and app-specific SAP Fiori UI components including SAP Fiori launchpad and SAP Gateway. To launch SAP Fiori apps using SAP Fiori launchpad, users are required on the front-end server.
Users must have the same user names on the ABAP front-end server and the ABAP back-end server. User mapping is not supported. For this purpose, you can use Central User Administration (CUA) or identity management systems.
To access SAP Fiori apps, users on the front-end server require UI content and authorizations. The corresponding PFCG roles need to be assigned to the user.
For information about the required UI content and authorizations for users on the front-end server, see Setup of Roles.
