                  Note: Hiding the item is not the same as removing it from the display. You cannot view removed items until the catalog search filter
                     is refreshed, by using the 
                     				Refresh option or by logging off and back on to the mainframe, at which time, the removed items are located again by the catalog
                     search filter.
