When checked in files are saved by an internal editor

This ClearCase SCM Adapter preference specifies Rational ClearCase behavior when you attempt to save a Rational Developer file that is not currently checked out.

If you want ClearCase to check out files without being notified, select Automatically checkout. The automatic checkout process is necessary for Rational Developer operations such as refactoring. If you do not want ClearCase to automatically check out files, select Do nothing.

You cannot change the activity that is associated with the file during the automatic checkout. To change the activity associated with a file, you must check out the file directly.

Attention: If you are using a shared branch in a dynamic view, the automatic checkout process could create a potential conflict. While you are editing a file that is not checked out, another project team member can check out, edit, and check in the same file before you attempt to save it. When you save the file, the automatic checkout process silently checks out the latest version of it and when you check in the file, your edits overwrite the previous edits made by the other team member. To avoid problems, always check out files before editing them.

By default, this option is set to Automatically checkout.
