Using this check box, you can activate/deactivate the authorization via SQL.

If activated, the authorization via SQL is used for business objects in catalogs and for API. In most cases, it significantly improves the speed of data reading from database, because only data authorized via SQL query are transferred from the database.

Note: The authorization of calendar events works just in case the authorization works for the corresponding Object Type. Now the Calendar Events are authorized in such a way so that the only visible Events are those for which the "source" object or the underlying objects have been authorized. Please keep in mind that the authorization through transient attributes or relations leads to an unexpected result as the handling of calendar events is clearly database-oriented (not 'in-memory')!
