@OnuAn The completion date for the tasks is automatically marked by the planner once the task is marked as done. You don't need to manually mark this. To view the task completed date and user, export the Plan to Excel.
I@Santhosh Balakrishnan That's a false assumption i.e. that the day closed is the completion date given that the task may be closed days after the actual completion date. It would be a good field to have in order to track "actual" completion dates. Thank you for the feedback.
