Novell ZENworks 7 Server Management Support Pack 1 - ZSM7 SP1 Tiered Electronic Distribution (TED)
The "Help" screen in ConsoleOne talks about an option: "Delete Previous Revision Before Receiving Next" which it says will show up when max revisions is set to "one". This option never appears in ZEN7.
Fixed in ZENworks 7 Server Management Service Pack 1 Interim Release 3a, see KB 3809227 "Updates to Novell ZENworks 7 Server Management" which can be found at https://www.novell.com/support
This was an option that existed in previous versions of ZENworks but does not exist in ZEN7. The help screen has been corrected in ZSM7sp1HP1 and later to not include this invalid information.
