GP Fault on Undo After Adding Resource to Multiple Projects

 * }

Q126797

-

The information in this article applies to:


 * Microsoft Project for Windows, versions 3.0, 3.0a, 4.0

-

SYMPTOMS
In Microsoft Project, if you add a resource to selected tasks located in different project files, and you then choose Undo Entry (Undo Assignment in version 3.0) from the Edit menu, you may receive a general protection (GP) fault.

CAUSE
This problem occurs if you share a resource pool among two or more projects, and you select tasks from the different projects, and then assign a resource to the selected tasks. The resource is assigned across the different projects correctly. However, if you choose Undo from the Edit menu, to undo the assignment, you receive the GP fault.

WORKAROUND
To avoid receiving this GP fault, use any of the following methods.

Method 1
When you want to assign a resource to multiple tasks across projects, assign the resource to the tasks individually, instead of assigning the resource to a selection of tasks.

Method 2
If you have already assigned a resource to selected tasks across multiple projects, remove the resource from the tasks individually, instead of choosing Undo Entry from the Edit menu to remove the resource.

STATUS
Microsoft has confirmed this to be a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION
NOTE: To select tasks across multiple project files, you can do the following:


 * 1) Share resources across multiple project files.
 * 2) In one of the project files, choose Split from the Window menu.
 * 3) Select the view in the Upper pane, and choose Resource Sheet from the View menu.
 * 4) Select the view in the lower pane, and choose Gantt Chart from the View menu.

When you select a resource on the Resource Sheet, the tasks to which this resource is assigned are displayed on the Gantt Chart. You can then use the SHIFT key or the CONTROL key to select multiple tasks on the Gantt Chart.
