[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.
