i want to modify database table in another R/3 system through RFC, what's the prerequisite ? both the server and client system are R/3 4.7 , and the RFC works fine in server when tested through F8.
First BC team build an RFC destination. (SM59)
Then you develop and RFC enabled function module in target system (or use an existing one), and a module/program driver in the source system
The program in the source system call the function module in the target system via RFC (destination parameter)
If the logon is not hard-coded in the RFC link, and the system are not trusted ones, a window will appear to log in to the system.
