You can schedule a workflow to run continuously, repeat at a specified time or interval, or you can manually start a workflow. By default, workflows run on demand. You can create a non-reusable scheduler for an individual workflow. Or, you can create a reusable scheduler to use the same schedule settings for all workflows in a folder.

If you configure multiple instances of a workflow, and you schedule the workflow run time, the Integration Service runs all instances at the scheduled time. You cannot schedule workflow instances to run at different times.
