There is something that must be very clear when setting up security for Views. In order for a User/Group to have access to a task or document they must be allowed access in the Folder where the task/document is stored. For example Group Z has no privilege to access Folder 1. Then you can not create a Views which includes documents from Folder 1 and give Group Z privilege to these documents. To setup the Views Security highlight the Project from the Project Center select Reports…Views. Right mouse click the View Folder then select Security will bring up the Privilege screen.
Read View/Read Tasks – Allow Read privilege to the View, Tasks and/or documents in the View.
Add/Delete/Modify Views – Add, delete or modify a sub Views of this View.
Add Task/Document Links – Add tasks or documents to the View, called links because the document actually resides in a folder and is only linked to Views.
Delete Task/Document Links – Delete Tasks/document links from this View.
Assign Privilege for this View and Sub Views – Assign privilege to this view to other Groups or Users.
