How does the 'Auto-shift Successor' option, available during Autoscheduling work?
Resolution
After this toggle is set to true, if any task is dragged in the timeline to a different place, then its successors will also shift. The same happens if you change the date on it as an alternative.
If this toggle is set to false, then if a task is dragged to a different place in the timeline, then its successors will remain where they were. Same behaviour when date is changed.
Simply setting the toggle to true does not move any tasks.
