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

  1. 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.

  2. 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.
