Security is critical for your business data. Typically, you don’t want everyone in your company to have access to all the data. All the standard security features used with PeopleSoft applications are integrated in the PeopleSoft Query, as well as the query classes.
In addition, you can use the QuerySecurityProfile Class to view the current user's security profile for PeopleSoft Query. This class doesn't contain any methods, and all the properties are read-only.
