Oracle Preventive Controls Governor is a set of four applications that run, and implement controls, within instances of Oracle E-Business Suite: Form Rules modifies the security, navigation, field, and data properties of Oracle EBS forms. Flow Rules defines and implements business processes. Audit Rules tracks changes in database tables that underlie Oracle EBS. Change Control regulates changes to field values in Oracle EBS forms. In the background, Preventive Control Governor also provides "preventive analysis" functionality employed by a separately installed product, Application Access Controls Governor.
