Register a program locally with rfcexec

Earlier when we tested the RFC with external Ferrari (FAX) server it failed but when we registered the same RFC locally on central ZE1 server the RFC started working the command we used was as follows:

rfcexec -aZE1.100.ferrari -gR3-ZE1 -xsapgw01 &

here rfcexec is a program to register rfc

ZE1.100.ferrari is the name of RFC connection

R3-ZE1 is the hostname where we are registering the RFC program

sapgw01 is the name of the gateway

& the program is running in background
