Sometimes you need to detach a label from an item in a rolled-back view. For example, suppose you deleted a file that had view labels attached to it. Later you created a build label based on one of the view labels that was attached to the deleted file. If you roll back the view to the new build label in order to perform a build, the deleted file reappears in your view. If you do not want that file in this build, you can detach the new build label from that file. If you try to detach any other label from the rolled-back view, an error message informs you that you can detach only the label to which the view has been rolled back.
The item from which the label is detached will disappear after a refresh.
