Q:

Hiding/Blocking revised file information in a changelist

On P4V windows app,I can select a particular user and a workspace and see the user's list of changes on that particular workspace. When I click a particular changelist from the list of changes, I can see the changed files under the 'Files' tab and then see the actual revisions for a particular file. 
For some reason I cannot see the revised file named in some rare cases and when I click on files tab I see a message saying changes might protected or obliterated. Is it possible to do something to prevent other users from finding out what changes you have made for a particular changelist?

A:

Yes it is possible. A changelist may be marked either public or restricted, and a restricted changelist requires permission to view: http://www.perforce.com/perforce/r10.2/manuals/cmdref/describe.html#1040665. It is the 'type' of the changelist that controls this: http://www.perforce.com/perforce/r10.2/manuals/cmdref/change.html#1040665
