OnCommand Workflow Automation (WFA) provides two scheduling options for workflows. You can either schedule a workflow to execute once at a specific time or you can create recurring schedules and associate the schedules to workflows so that the workflows are executed routinely.
The resource and execution planning for the workflows that are scheduled to execute once are done immediately when the workflows are schedules. However, the resource and execution planning for the workflows with recurring schedule occur at the scheduled time and not when the schedule is associated with a workflow.
