From within the Execution Queues window, click on the Monitoring tab to see status information for the playback.
This shows information on (reading clockwise from top-left) the currently-running execution queue blocks; the active Bot(s); the jobs that are running in the central system to manage the playback; and the most recently executed steps.
You can refresh the top-level to update all the individual results windows, or you can refresh each window independently. You can also log into the Target system to view currently running activities.
If you have visibility of the bot machines, you should start to see the bots performing the playback steps. This might be via the SAP GUI, but equally the console will show you if it is running other steps such as RFC’s and batch jobs.
