Why does the Default Saved Search field display with either no name or with a Select drop-down list?

If you don't have permission to view the object associated with the default saved search references, then the Default Saved Search field in the Manage Saved Searches Defaults by Role window is either empty or contains the word "Select".

Let's say you don't have permission to view the Partner object. A role name such as Channel Account Manager, who has a Partner default saved search assigned to that role, will not display in the Default Saved Search field. In addition, saved searches that you don't have permission to access do not appear in the Default Saved Search drop-down list.

To view the assigned default saved search, or to assign a default saved search to a user role, you must have permission to view the object underlying the saved search.
