You require two types of RFC connections to the back-end system:
An ABAP connection (type 3) which is used for to replicate app descriptors from the back-end server to the front-end server. Applications which use Web Dynpro UI technology carry app descriptors which provide information required to access them from the SAP Fiori launchpad.
An HTTP connection (type H), which is used to start transactions using Web Dynpro and retrieve the business data.
Note
For technical reasons, you also need these RFC-connections if front-end components and back-end components are running on the same system.
Create an RFC connection of the “ABAP Connection” type and one of the“ H - HTTP connection to ABAP System” type. Use the following naming conventions:
ABAP connection: S4FIN_RFC
HTTP connection: S4FIN_HTTP or S4FIN_HTTPS
Recommendation
We recommend that you use an HTTPS connection. Set the SSL option to Active.
