What are the dependencies between a subtask and a previous task?
- You cannot change a subtask if it has a previous task. You cannot change its status to ‘Completed’ or modify its start time.
- During the creation of a subtask, the start date and time of the subtask are set to the due date and time of its previous task.
- If an existing subtask with no start date and time are edited and linked to a previous task, then the start date and time are updated with the previous task's due date (if specified).
- If an existing subtask whose start date and time are specified is edited and linked to a previous task with no start date and time, then the start date and time of the subtask are not overwritten by the value specified in its previous task.
- You can mark a subtask as completed only after completing its previous task.
