To close a patch number so that no more changes can be made in that version
In the Patches Browser, select the open patch number that you want to close.
Select the Close command from the Patches menu.
The Close command is disabled when you select a patch number that is already closed.
The selected patch number is then closed and the user id of the person who closed the patch and the date on which it was closed are displayed in the Patches Browser for that patch number.
When you attempt to close a patch number to which other users are currently set, a message box is displayed, stating that the patch number cannot be closed and listing the other users who are set to that patch.
