Determining whether a study object is locked

Only the user who holds the lock can modify a study object. The following types of locks are available:

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

To determine whether a study object is locked:

• In the Project Explorer, view the icon for the study object.
  • Normal icons appear for unlocked study objects.
  • Shaded icons appear for locked study objects.
    • If the lock icon is green, you hold the lock.
    • If the lock icon is red, someone else holds the lock. The tooltip for the study object has the name of the user who holds the lock.

      Note: The Modified property in the tooltip indicates whether you modified the study object since the last time you saved it. If someone else holds the lock, the property is set to False.

  or

  In the Properties Browser, check whether the Locked property is set to True or False.
