Undoing a ClearCase Checkout

If you have checked out a file but not made any changes to it, or if you want to discard the changes you have made, you can undo the last check out of that file.

Caution: you may lose you work if you use this on a file that you have changed since it was checked out.

To undo checkout for one or more files:

Select the files in the navigator, and choose Versioning Undo Checkout. The Undo Clearcase Checkout dialog is displayed listing the items you have selected.
To undo the checkout for all the listed file, and lose any changes that you have made to those files, click OK .
