You can schedule workflows in the Workflow Monitor. You can schedule any workflow that is not configured to run on demand. When you try to schedule a run on demand workflow, the Workflow Monitor displays an error message in the Output window.
When you schedule an unscheduled workflow, the workflow uses its original schedule specified in the workflow properties. If you want to specify a different schedule for the workflow, you must edit the scheduler in the Workflow Manager.
To schedule a workflow in the Workflow Monitor:
Right-click the workflow and select Schedule.
The Workflow Monitor displays the workflow status as Scheduled, and displays a message in the Output window.
