Unlock the schedule
When a schedule is being used in the deferred mode, Teamcenter displays a lock icon.
The schedule can be unlocked by the following users:
- The user who has the schedule running in deferred mode.
- The coordinator of the schedule.
Procedure
Choose Schedule→Deferred Session→Release Session.
Teamcenter displays a warning about losing changes made during the deferred session.
Caution: This should only be used when a lock got accidentally left; not when a person is working in a deferred mode.
Click Yes to unlock the existing deferred session, or No to continue the existing deferred session.
The schedule is automatically unlocked for any of the following reasons:
- You exit the deferred session.
- You cancel the deferred session.
- The deferred session times out.
