A checkout is a private copy of a Rule- instance that you update and later check in to replace a base rule version. All checked out rules reside in a ruleset that is only visible to your operator known as your personal ruleset.
Two types of checkouts are supported:
Before you start, verify that your operator allows rule checkout and the rule resides in a ruleset with checkout enabled.
The Private edit option is available when your operator has the pxAllowPrivateCheckout privilege. A private checkout is like a standard checkout except it does not block checkouts for other users. This option is good for quick debugging without interrupting development by other team members.
