Installing SAP RFC DLLs on OS/390 system to support remote RFC call

We are in the planning process for a project to invoke a SAP RFC function on a remote SAP 4.7 to sign out a part number. The calling system (invoking the RFC) will be an IBM mainframe running OS/390 and the called system is SAP 4.7 running on a Unix server. Would you have any advice (or referrals) in determining the pre-req's and the documentation for installing SAP RFC DLLs on the OS/390 system to support the remote RFC call?

The solution of choice would be sending the data as HTTP POST request to SAP Enterprise.

If you want to use RFC from OS/390, everything will be in the basis admin. guide. However, this is a complicated procedure and sending the IDoc in the HTTP body for 4.7 is just as good and very simple.

For an arbitrary solution, you can then write a small BSP in 4.7 that in turn calls the IDoc handler.
