Start Dates Do Not Change When Predecessor Changed (MSP Pro 2002)

When the Predecessor Task is changed the start dates do not change for Successor tasks. The tasks are set as Fixed Duration, not effort driven. The only way to change the start date seems to be manually set the date.

If the finish date of a predecessor task is extended then the start date of successor tasks will move forward if the dependancy relationship is Finish to Start, or Start to Start. Exceptions would be if you have constraints applied to the successor tasks. You could look at the Constraint dates table or for the constraint icons in the indicators column. You should not need to manually type dates in the Start or Finish fields for any tasks in the task entry table. If you manually type dates in these fields Project will automatically apply constraints for you. The default constraint applied to all tasks is As Soon As Possible. This means as soon as possible honoring dependancy relationships and any non-working days applied to the Project base calendar, or from a resource calendar for an assigned resource. If you have constraints you do need you can return to the default As Soon As Possible and change the constraint date to NA. Project will not accept N/A.

I did not have constraint dates but I did have % complete > 0 for some of the tasks. Apparently MSP will not reschedule a task that has started.

If the successor task has any % complete the task has an actual start date and will not move dynamically.
