System-Operation-Track Gantt Chart

It is possible to display several systems in the System-Operation-Track Gantt chart.

You can directly select one or more systems, select an operation (in this case the first parent system is displayed), or select a track under an operation (in this case the first parent system of the operation is displayed).

If no system, operation or track is selected, all the root systems loaded in session in the current editor are displayed in the Gantt chart.

When several systems are selected (directly or indirectly), a check is done to verify if a common parent system exists to avoid multiple display of same system.

Dragging a System or Operation

It is possible to drag a system or operation on a system or operation to create product flow constraints if both dragged objects have a common parent system. This common parent System must exist in session but it is not necessarily displayed in the current Gantt chart.
