entire package hierarchy &V2& because
either the root package &V3& of the provider package hierarchy does not
supply any filter package interface or
the root package &V4& client package hierarcy does not have any use
access entered for this filter package interface.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

A virtual standard package interface or a package interface of a main or
development package of the first non-structure package is not visible

use access entered for this filter package interface.
