On the left navigation Menu, click System > User Management > Manage Users.
From the Manage Users table, edit the user record for the person whose permissions you want to change (either double-click on the user or select the user and click the blue Edit action button).
In the User record there are several checkboxes under the blue “Permissions” header. Selecting and deselecting these checkboxes sets different permissions for users. NOTE: For more information on each permission level you can hover over the blue question mark to the right of the permission.
When your selections are complete, click one of the green Save action buttons.
