From fact sheets, you can access the back-end server and start transactions there (in SAP GUI or Web Dynpro). To enable this, you need to establish a connection between the SAP Fiori launchpad and the back-end system. Perform the following steps on the front-end server:
From mobile devices or tablets, you cannot access SAP GUI or Web Dynpro transactions through the SAP Fiori launchpad.
Run transaction Overview of Launchpads (LPD_CUST) on the front-end server.
Select the relevant role with Instance TRANSACTIONAL and double-click it.
There is a role for each front-end application. Select the front-end application that corresponds to the back end for which you want to define the RFC connection. Example: You want to establish an RFC connection that enables users to run the transaction Display Purchase Order in the SAP SRM back-end system. In this case, you need to select the role corresponding to the SAP SRM front-end application.
In the left-hand screen area, select a row where Transaction is displayed as the Application Description. The system alias is displayed in the right-hand screen area.
Use the system alias identified under 1. as the RFC Destination.
