Have you checked the logs? Or does the process not start at all? Maybe the timing is wrong or the process is not assigned to a resource (within the task that is assigned to the schedule). My first advice for all troubleshooting is to look around very carefully in the window for all options and settings.
i have an issue in scheduling a process. it shows the pending symbol in the scheduler part, but at the exact time to start it changes to red sign indicating it didnt run. I have checked the log but it brings the error of "time out waiting for valid connection". Kindly help with a solution. Thanks.
