Basic doubts Regarding the RFC to File scenario.

Hi All,

I'm doing a RFC to File scenario, so before starting the development i went through many blogs and sites to know more the about scenario. I'm confused in the step where we have to create a RFC (type TCP/IP) in sm59.

I have the following doubts :

1)whether to create the RFC in sender (which will be ECC system) or XI.

i.e., RFC in sender (ECC) pointing to xi system in sm59 of Sender(ECC)

or

in XI pointing to sender (ECC) system.

2) the program id maintained in RFC.

the program id is any name or the FM which is being imported in XI system.

Thanks in Advance,

Kind Regards,

Lalitkumar.
