As discussed inR80.20 security checkup report does not export, there is problem in R80.20 GA to export in SmartView the "Security Checkup - Advanced" report.
The issue will be fixed in the next JHF, which should be released in the following weeks.
It can be fixed by placing the attached file (reports.xml) on the management server under the folder $RTDIR/smartview/db/predefined/
(create the folder if it doesn't exist), and restart of SmartView:
$RTDIR/scripts/stopSmartView
$RTDIR/scripts/startSmartView
