Undoing a deliver operation

At any time before developers complete the deliver operation, they can back out of it and undo any changes made; but if they check in their versions to the integration view, they cannot undo the changes easily. When this happens, you may need to remove the checked-in versions by using the cleartool rmver –xhlink command.
Warning: The rmver command erases part of your organizational development history, and it may have unintended consequences. Therefore, be very conservative in using this command, especially with the –xhlink option. See the rmver reference page.

Removing a version does not guarantee that the change is really gone. If a successor version was created or if the version was merged before you removed the version, the change still exists. You may need to check out the file, edit it to remove the change, and check the file back in.
