   Now browse to {System.List} in the Class Browser and open the MetaClass SELECTIVEITEM in the Bulk Editor (via Drag & Drop).
   
   
   Every row in the Bulk Editor is shown greyed and can´t be edited, because the MetaClass SELECTIVEITEM is a system MetaClass. So we need to enable the Admin mode.
