Procedure documentationLooking Up the Rules Engine Locate this document in the navigation structure

 

You can look up the Rules Engine either locally or remotely or both depending on whether your rules are built on XSD or Java or both. You can do the remote lookup only when your rules are built on XSD. You can only do local lookup when the rules are built either on Java or Java + XSD. The table below illustrates the lookup possibilities.
