A lock is a feature of Windchill RV&S that controls how changes are made to revisions. When a change is checked in, it requires the revision being updated to be locked, in order to prevent more than one user from simultaneously checking in changes to the same revision.
Normally you lock a member during a checkout. Sometimes, however, you may have made changes to a working file that was not checked out in your name first. In this case, you can set a lock without overriding your changes.
To lock a member, select the member or revision in the GUI, then select Member > Locks > Lock.
The person who has a revision locked is referred to as the locker.
You can upgrade your lock from a non-exclusive lock to an exclusive lock in the Locks view.
The following are the options on the Lock Revision dialog box:

• To obtain a lock type based on the locks policy, select Follow Policy. For information on the locks policy, contact your administrator.
Downgrade Lock Request on Conflict
