Every report that you store in BusinessObjects Enterprise uses managed
list-of-values objects. All managed list-of-values objects are based on a
Business View, even if the report itself does not use a Business View.
Managed list-of-values objects have a number of features that are not
available to unmanaged list-of-values objects.
