Hi, folks!
When you deploy DeepSee solutions you often do not want grant a User %All Role to work with a particular Dashboard.
Consider a Dashboard 'Dash' with a few widgets where listings are being used.
If you manage a Role to get access to the Dash you need to grant access to %DB_DBNAME resource to have a database access, grant access to a Dashboard resource (if any) and ... grant SELECT accesses to all the tables involved in SQL queries being used in all the listings of widgets.
