These are the rules for using the Auto-update Activity Data checkbox.
- The Auto-Update Activity Data checkbox is unchecked by default for all schedule sheets.
- As soon as a new BP is set up for the activity (by choosing File > Setup Scope Management), the Auto-update Activity Data checkbox will be checked only for activities in the Not Started status.
- Updating the BP setup on an activity later will only check the Auto-update Activity Data checkbox automatically if the activity is in the Not Started status. If you have not set up any BP linking, by default, the box is unchecked. In that case, you can update the Actual Start, Actual Finish, and Status fields.
- You can manually modify the Auto-update Activity Data checkbox for any activity status, including complete.
