Renaming a Work Item
Once you create a work item, you can edit the name of the work item.
You can only rename a work item if you are the owner of the work item or an administrator.
To rename a work item
- Select a Work group from the Work groups section.
 - In the Work Items list, select the Work item you want to rename.
 - In the Details pane, click 
Edit. - Type the new name in the Name field.
 - Click Save changes.
 
The work item's name updates to the new name. The Updated date changes to A few seconds ago, to reflect the time of the update.
Restrictions on work item names
You cannot create or edit a work item so that its name contains only whitespace characters. For example, spaces, tabs, next line characters, and so on. Whitespace characters at the beginning and end of a work item name are not removed when saving a name.
