Folders and items can be shared from one view into another if both views belong to the same server configuration. They can also be shared from one folder to another within the same view. When you share folders and items that can branch, they acquire branching behavior in the new view. Requirements, tasks, and topics do not have branching behavior.
An item’s behavior determines whether the item branches on change. A shared item’s initial behavior in the new location depends upon the setting of the “Set items shared into view to branch on change” property when the item was shared. This view property appears on the View Properties dialog box in the root view and in branching views, but it does not appear in reference views. In reference views, the behavior of the shared folders and items that can branch depends on this property’s setting in the parent view of the reference view.
After items have been shared into a view, you can change their behavior on an item-by- item basis, but additional changes to the Set Items Shared Into View To Branch on Change property do not change the behavior of the items.
