Fiori Data flow in Front End server


SAP ABAP Front-End server contains all the UI components of Fiori system and NetWeaver gateway. These UI components consist of central UI add on, SAP UI5 control library and SAP Fiori Launchpad. When Launchpad is called, the app reads Launchpad definition via OData service call.

  • It contains all the OData services, UI and Launchpad objects.
  • Users are defined and required roles are assigned in Front End server.
  • It interacts with Back End server using trusted RFC connection and system alias to communicate with Back End.
  • Fiori apps gets data by calling OData service. The data from Back End is pulled in the apps through the Front End gateway system.

Fiori Data flow in Back End server

SAP ABAP Back-End Server contains the SAP business suite which provides business logic and the back-end data.

  • The back-end server is based on SAP NetWeaver.
  • It contains users, roles and authorizations.
  • Users should have an authorization S_RFCACL that performs Authorization check for RFC users, particularly for trusted systems.
