Define Subproject Task Options

Use the Subprojects tab of the Task Properties dialog for a selected subproject or an external task to review or change the subproject options.

Note the following when editing subprojects and subproject tasks in a master project:

The changes you make to subprojects are reflected at the master-project level when you open the master project next, unless you have both the master and subproject open simultaneously.
If you inserted the subproject as read-only into your maser project, you can edit its option, but the changes you make cannot be saved.

Follow these steps:

Right-click a subproject task in the view and click Modify in the shortcut menu.
Open the Subproject tab.
Complete the following fields, and click OK:

Project

Review the subproject's name.

Read-only

Select to display the subprojects as read-only in the master project.

Note: This field displays as read-only and is unavailable if you inserted the subproject task as read-only.
