To transfer application data and security credentials within your SAP Fiori system landscape, communication between the client, the front end, and the back end is established by using different communication channels and protocols:



Figure 1: System Landscape with ABAP Environment: Communication Channels

Communication Between Client and ABAP Front-End Server

For transactional apps, the client can issue the following types of requests to the ABAP front-end server:

  • HTML requests

  • OData requests

For communication between the client and the ABAP front-end server, an HTTPS connection is established.

Communication Between ABAP Front-End and ABAP Back-End Server

For transactional apps and fact sheets, data and services from the ABAP back-end server are provided to the ABAP front-end server by using OData services. For communication between the ABAP front-end server and the ABAP back-end server, a trusted RFC connection is established.
