You can use the Undo changes in selected tests 
function to undo changes made to test results since the most recent Save. When you undo changes, the test status also reverts to that which existed before the most recent Save.
To undo changes:
- In the main panel, click the check box to the left of each test result for which you want to undo changes.
- Click Undo changes in selected tests in the Batch details view toolbar.
