CTRL+O to access time database. This show the time records attached to the order, even if the labor has been removed. In this screen you are able to edit the time database, this is the techs time, and should not be edited unless the time is incorrect, you are also able to move to another order, and lop.  Removing punches manually with the F5 while lined up on the item should be used with caution.

Note: This will then be removed completely from the system not just the order.  The techs time will not be accounted for at this point.

again use with caution
