Pass Parameters to Rule Flow Activity

To pass in parameters to be used within a Rule Flow Activity, follow the steps below:

  1. In the Project Browser, double-click on the Rule Flow Activity. The element Properties dialog displays.
  2. Click on the Behavior tab.
  3. Click on the Edit Parameters button. The Parameters dialog displays.
  4. Create and define each parameter, setting Type and Default values.
  5. Save each parameter and, when you have finished setting the parameters, close both dialogs.


The Rule Flow Activity parameters can be accessed by the Rule Tasks within the parent Rule Flow Activity. In the following hierarchy, the parameters m_rent and m_application can be used by any of the Rule Tasks under the ProcessApplication Rule Flow Activity.


You can use the parameters as condition variables or action variables in the Business Rule Decision Table, or as rule variables in the Computation Table for any of the Rule Tasks. If the Activity parameter is not accessible to a Rule Task, Enterprise Architect displays an error message.
