For most attributes of a project, the attribute is relevant only to a task, and not to a superproject. Therefore, the corresponding cell in the Attribute table is not editable for a superproject. For some attributes, however, a mechanism is provided, by which the user can edit the attribute for the superproject as a convenient way of changing the attribute for its entire subtree of tasks. The attributes for which this feature is available are Assigned To, Percent Complete, Level Resources, Splittable and Squeezable.
Editing the Assigned To value is discussed in this section.
Editing the Percent Complete value is discussed in this section.
Editing the remaining three attributes is quite similar and we discuss only Splittable here, as an example. To edit the splittable value for an entire subtree of tasks, double click the Splittable column for the superproject at the root of the subtree:
the editing dialog shown below appears. Click the checkboxes of the projects for which you want to set the value.
projects for which the value cannot be changed (for example, started projects) are grayed out, as shown.
clicking the Check Scheduling button after making changes brings up a visual display of the changes to the start and finish dates that your current changes will effect.
click the Save Changes button to save your changes.
