About locking data-entry rules, workflow rules, and global conditions

You lock study objects and rules, including data-entry rules, workflow rules, and global conditions, independently of each other. Only the user who holds the lock can modify a data-entry rule, workflow rule, or global condition. The following types of locks are available:

• An automatic lock, also known as an implicit lock, is applied to a rule when you modify it and is released when you cancel or close without saving or when you save the study object or the project.
• A requested lock, also known as an explicit lock, is applied to a rule when you explicitly lock it and is released only when you unlock the rule. You might request a lock if you plan to work on a rule for an extended period of time.

Note: A lock icon is red if someone else holds the lock and green if you hold the lock. To view details about the lock, including the person who holds it, point to the lock icon.
