Before canceling a deliver operation
Any time before completing the deliver operation, you can cancel changes made as a result of the operation. This cancel procedure is valid only if you have started a deliver operation, have not checked in modifications in the target view, and have not completed the deliver operation.
A cancel deliver command is provided, which cancels all checkouts in the integration view and removes all merge arrows created during the current deliver operation. (Merge arrows (hyperlinks) in VOBs are used to keep a history of merges.)
If you checked in any versions to the integration view, using the cancel deliver command is not sufficient to cancel the deliver operation. In this case, you must either complete the operation (recommended) or use cleartool rmver -xhlink to remove the versions you checked in before canceling the operation. Because rmver erases part of your organizational development history, your organization might not allow individual developers to use it. Be very conservative in using this command, especially with the -xhlink option, which might have unintended consequences. For more information, see the deliver and rmver reference pages.
