SYMPTOMS
If a task is marked as being 100-percent complete in Microsoft Project, any changes to the actual start or actual finish dates will not affect the scheduled start or finish dates for any resources assigned to that task.

WORKAROUND
If you find that you need to alter a task's information after it has been set to 100-percent complete, but you want the resource schedule to reflect these changes also, do the following:


 * 1) Enter a value less than 100% in the task's Percent Complete box.
 * 2) Make any necessary changes to the task.
 * 3) Change the task's Percent Complete box back to 100%.

MORE INFORMATION
When a resource is first assigned to a task, Microsoft Project calculates a start and finish date for the resource on that particular task, based on the scheduled work for the resource, the scheduled dates for the task, and any pertinent calendar information. As long as the task is not 100-percent complete, any changes made to the scheduled start or scheduled finish of the task will cause the resource's schedule to change accordingly.

If a task is 100-percent complete, Microsoft Project disassociates the resource assignment information from the task information to allow you to make manual adjustments to some resource fields, such as Actual Work, without affecting other task information. One result of this disassociation is that the resource's schedule is no longer tied to the task's schedule, so changes to the task schedule have no effect on the resource.

For an example of this effect, do the following:


 * 1) Create a task called task1 with a duration of 1d. Select Must Start in the Constraint list box and type 7/1/91 8:00am in the Date text box below the Constraint list box.
 * 2) Assign a resource named resource1 to task1 with 8 hours of work.
 * 3) In the Task Entry view, click the task form at the bottom of the screen, and then choose Resource Schedule from the Format menu.

The task form should show start and finish times for resource1 that correspond to the scheduled start and scheduled finish times for task1.
 * 1) Change task1 to 100-percent complete by typing 100% in the Percent Complete box.
 * 2) In the Task Form, choose the Actual button below the date section. Change the actual start time by typing 7/3/91 8:00am in the Start box and selecting Actual, and change the actual finish time by typing 7/3/91 5:00pm into the Finish box and selecting Actual.

Note that although the task dates have been altered, resource1 is still showing the original start and finish times.
