I have a user that Customized the Summary (HOME) page for SAM. Now the user would like to get the default back. I do not believe they made a copy.
installed a Trial version to see what the default settings are.
Installing an eval on a temporary server is the least impactful method.
The only other way I know is to delete that specific view from the database table and rerun the Configuration Wizard (selecting the Database option). It will run a repair and replace any missing views. This does mean taking the system offline while the wizard runs the repair.
