Updates are reverted when attempting to update a Project tasks Planned End Dates or Planned DurationIssue Updates are reverted when attempting to update a Project tasks Planned End Dates or Planned DurationResolutionThe issue occurs when the "Actual Duration" field is set to "0" instead of "Empty/NULL" when the Project Tasks were imported via import set. Per base system logic, the Planned End Date = Actual Duration + Planned Start Date if Actual Duration is not equal to NULL. The issue can be resolved by updating the value of the affected tasks "Actual Duration" field value to "NULL" rather than "0" via script or by setting the Actual Duration value to NULL/Empty when importing the Project tasks.
