The form originator or HR can replace a task assignee on a task.
If a task is in progress, first click "Mark as Incomplete" to be able to change the task assignee.
On changing a task assignee, you have the option to:
- Retain the existing data (Electronic Forms, etc.) filled out by the task assignee being replaced by clicking "Yes" or
- Delete the data filled by the task assignee being replaced and have the new task assignee complete the data from start, by clicking "No"
