You can add an assignment result to an event rule.
To add an assignment result:
2. Do one of the following:
a. Right-click any result and select 
Add Assignment from the context menu. b. Click Assignment in the Palette view. Drag and drop, or click and drop it either before or after an existing result. c. Click in the toolbar. 3. In the Parameter Element Selection dialog box, select a parameter element from the list of available parameters.
Note: Each parameter element must be unique in the event rule.
To add a new parameter, click
Add Parameter. In the
Create Parameters dialog box, proceed as described in
Adding a Parameter to a Decision Entity and specify the parameter as input/output parameter. The added parameter is then selectable in the
Parameter Element Selection dialog box.

If you add an assignment result with the context menu or the toolbar, it is inserted after the last result row. Otherwise it is inserted in the place where you drop the cursor.
