Dear Ram,
Hope you know SM59 - to create the RFC Destination.
Name the RFC destination of one server as say - RFC-TO-SERVER1.
The main program that calls the RFC destination will be looking like this. I hope bapi_user_change is rfc enabled.
You need to add the DESTINATION parameter only.
REPORT zrfc_job
CALL FUNCTION <YOUR RFC NAME>
DESTINATION <RFC-TO-SERVER1>
EXPORTING
<YOUR INTERNAL TABLE>....ETC.
Please let me know if you need any information
Regards,
Venkat
