Parameter Element | You can only select an element of a parameter that is used in the event rule and specified as input/output. |
Data Model Element | You can select any data model element. If no parameter specified for the event rule contains this element, a new input/output parameter is created automatically and listed in the Rules Explorer view. If one or more parameters specified for the event rule contain this element, a Parameter Selection dialog box prompts you to select the parameter this element should be associated with. The dialog box lists only the parameters that contain this element and are specified as input/output parameters. The Parameter Selection dialog box enables you to add a new parameter as described in
Adding a Parameter to a Decision Entity. Added parameters that contain the selected element and are specified as input/output parameters are then selectable in the Parameter Selection dialog box. |
