Date constraints in schedules

When you set date constraints on work records, the constraints appear in the Gantt view.

Work date constraints are set in work management applications, for example, Work Order Tracking, Activities and Tasks, Changes, and Releases. The values in the Start No Earlier Than and Finish No Later Than fields on the work records are the date constraints.

After you create a schedule and save the data, you can view the work in the Gantt view. When you click a work record in the Gantt view, date constraints on the work record appear as red lines. The thin red line indicates the Start No Earlier Than date, and the thick red line indicates the Finish No Later Than date. If no date constraints are defined for a task, the task shows the date constraints of its parent work record.

In the Graphical Assignment - Repair Facility application, date constraints on the availability of the repair location show as well. The constraints appear as blue lines, the thin blue line indicating the start of the repair location schedule window, and the thick blue line indicating the end of the window.

You can adjust the dates in the Gantt view by dragging and dropping the work records, or by extending their duration. When you adjust the work dates, the Gantt view indicates whether the dates that you provided conflict with date constraints placed on the work or repair location. If you move the work to a date that conflicts with a constraint, the color of the work record changes to red. You can readjust the schedule dates to fall within the defined constraints, or you can override them and save the schedule.
