Facilitate SAP RFC Calls between two SAP Systems

Dear Community,

we have a existing Use-Case where we want to facilitate RFC Calls between
two of our SAP Systems.

SAP System 1 → SnapLogic → SAP System 2

The arrows simulate RFC Calls. For the connection between SAP System 1
and SnapLogic we use the SAP RFC Listener Snap that waits for the incoming
RFC Call. After that a new RFC Call should be sent to a Function in SAP System 2.
We were looking to use the “SAP Execute” Snap but we see that in only supports BAPI calls.

Is there any possibility to send RFC Calls so a SAP Systems with SnapLogic?
