From the Delta Browser, use the Close command from the Delta menu to close (remove) the selected delta.
When you close a delta that contains checked out methods, you are prompted to confirm that all checked out methods are to be checked in before the delta information is removed.
A delta can be closed only when all methods that were checked out to that delta are checked in and when no other users are set to that delta.
To close a delta
Select the Close command from the Delta menu.
If methods are currently checked out to the selected delta, a Confirm dialog prompts you to confirm that you want to check the methods in and then close the delta. Click the OK button to confirm that you want to do this or click the Cancel button to abandon the closure.
If no methods are checked out to the selected delta, a Confirm dialog advises you that there are no methods in the selected delta and prompts you to confirm that you want to close the delta. Click the OK button to confirm that you want to close the delta. Alternatively, click the Cancel button to abandon the closure.
When you click the OK button, any methods checked out to the selected delta are then checked in and focus returns to the Delta Browser, which no longer contains the closed delta.
