A [anchor]data date[/anchor] is an object on the canvas used to represent the date to which the project has been statused. Data dates help provide a clear visual indicator of the progress of the schedule. The data date appears as a blue circle with a blue line extending the height of the canvas on that date.
By default, the data date is set to the project start. When equal to the project start, however, it cannot be displayed or modified. Once a new data date is inserted, the prior data (if any) date will become faded, and if any un-actualized objects cross the data date, a red counter will appear in the upper-right corner displaying the exact number.
A data date cannot be moved on the canvas. If needed, it may be modified using the arrow keys on the keyboard or the Gestural Interface. For more info, see [bookmark postid=”8993″ anchor=”pushing-or-pulling-objects”]Pushing or Pulling Objects[/bookmark]. Likewise, a data date cannot be deleted. However, the most current data date may be reset to the project start. Instructions for this, as well as inserting, hiding, or showing the data date, are provided below.
NOTE: If working in CPM Mode, all activities to the left of the data date (or crossing through it) must have start and finish constraints applied before the data date is placed. Otherwise, the network (i.e. all connected activities and milestones) will jump to the data date (since this is where drift is calculated to) and be unable to be actualized. To set constraints globally for all necessary objects, see [bookmark postid=”8278″ anchor=”multiple-objects”]Bulk-Editing Objects[/bookmark].
NOTE: This will have the effect of deleting all previous data dates and de-actualizing all objects.
NOTE: Old data dates can only be displayed if the current data date is displayed.
