Determines whether the worklist folder is public or private.
Public folders and their contents are visible for all users assigned to this folder. These users can process the public folders.
Private folders and their contents can only be viewed and processed by the particular user assigned to them.
Worklist folders can be assigned to any number of users.
If more than one user is assigned to a private folder, each of these users has their own worklist folder of the same name, which can only be viewed and processed by that particular user.
