[1] Question: How can I test an RFC connection that has been set up?
Answer: In transaction SM59, "Display and maintain RFC destinations", you can perform two simple tests:
- For each type of RFC destination, you can test the connection by pressing the "Test connection" button. This is similar to the "ping" operating system command.
- To test the conntections to R3 systems, you can perform a "remote login". This is only successful with a user of the "Dialog" type and with valid login data a remote login is not possible for "Non-dialog users".
