To change an imported package
Select the imported package in the Import Packages Browser.
Select the Change command from the Packages menu.
The Import Package dialog is then displayed. For details about using this dialog to import a package, see "Adding an Imported Package to Your Schema", earlier in this chapter. When you are changing an existing imported package, the Select Package To Import combo box is disabled.
