Calling an RFC without the code being present on the destination system

Question

Hi All,
Here is my problem.
I want to execute a piece of code on a system from a program currently running on another system,
get the data and return back.
E.G. I am having a subroutine on development system. Let's say there is a select query inside the subroutine to get PARTNER from BUT000 based on certain parameters. The program should call an RFC get the data for the select query from the Production system and return the result back to the development system.
Please note : Here, I don't want to write the same piece of code on the production system.
<b>Is there any function module for the same or any idea on how to go about it.</b>
<b>Helpful answers would be rewarded.</b>

Hai
Sending system side(SEND--800)
Create function module by using Tcode SE37 or SE80
goto attributes select remote function
activate
Receiving system side(RECE--000)
goto Tcode SM59
here select the R/3 Connections-->click on Create Button
give RFC Desstination : TESTRFC
     Connection Type  : 3 for Connecting two systems
     Description      : Some meaningful Description
Press enter
give Target system Name : SEND
          Language      : EN
          Client        : 800
          user Name     : sapuser
          Password      : xxxxxx
save this connections & click on test connections(f8)
                      & Remote logon(f7)---> it will open a session
                        with client 800 that is your sending system
                        then only your RFC is correct
create a report in SE38 Tcode
data : c1 type i.
data : itab like mara occurs 0 with header line.
call function 'ZRFCFM' destination 'TESTRFC' --->Function Module 'ZRFCFM' your just create at Sending system
     exporting
     importing
     exceptions.
Thanks & regards
