While you are working on a document, you can lock it to prevent others from editing
it and then posting new versions to CollabNet
TeamForge .
When a document is locked, any user with the document view permission can view or
download the document, but only document administrators and the document creator can
post new versions to
TeamForge .
You can
lock a document when you create it or at any time afterward.
Note: Locking a document does not prevent it from being edited in its native
application.
