A behavior extension is a rule that is invoked whenever a transaction that matches the extension conditions is run.
The trigger events that you define for a behavior extension determine when it will be run. You can specify whether the behavior extension is run before (pre) or after (post) the triggering transaction. You can implement the behavior extension as a Java™ class or ODM rules file.
Behavior extensions are created in a module project.
For action or transaction events, you must also select the transaction that triggers the behavior extension to run. For action or transaction category events, you must select the required category.
After creating the behavior extension, additional associated code is generated.
