Forward scheduling In the Gantt tab, you can forward schedule the workflow dates. Change the Start Date for any open task. Press the TAB key. A push pin is displayed in the Fixed Date field. The Due Date is recalculated for the current step. Click Recalculate Dates. The Latest Start and Latest Due dates are recalculated for the current step. The Start Date and Due Date fields are recalculated for the upstream open tasks. The duration is used to recalculate the dates. When you recalculate the dates, the tasks before the fixed tasks are backward scheduled; and the tasks after the fixed tasks are forward scheduled.
