This feature is available in Enterprise and Ultimate editions.
The Detail Tracking page offers another place to update Status, Effort, and To Do. This is good for team members who might be transitioning from Excel, as it displays the information in a similar grid format.
Select Sprint Tracking, and then choose Detail Tracking. Double-click on a row to enable editing, enter your updates, and then click Save. To see workitems by a specific owner, you can use the Filter option.
Time entered in the system is attributed to the member logged in to the system, so it is usually easier for each team member to do their own tracking rather than trying to do it all together as a team.
