The Analytics Dashboard supports Role permissions for all list gadgets as well as drill-down dialog boxes for other gadget types. This uses the same permissions as the Screen Assignments as outlined in About Security Role Administration.
For example, if you want to prevent a user with the Field Worker role from accessing Labor Rates, you can go to Administration>Role Administration. Select Role>Resources>Labor and set rates to <None>.
For top-level recordsets, select <None> for the List screen assignment.
Some recordsets do not display the security settings dialog box, specifically Shared recordsets. These recordsets cannot have view security denied.
