Define Rule Actions
In the Classes in the Business Domain model, the attributes and operations that you set up to define the conditions through which a rule takes effect might in their turn call a decision attribute or an operation, which you can assign as an action in the Rule Actions (Outcome) table. You create the attributes and operations as you set up the Class, with at least some values or parameters, and you tailor some of these features to define the actions that determine the effect of the rule.

From the appropriate business term Class element in the Project Browser, drag and drop the decision attribute (such as Eligible - Yes/No) or operation (such as post error) onto the first empty field in the Rule Actions (Outcome) column.

For an attribute, if the dropped action variable is of type enum, the Allowable Values/Parameters fields are automatically set with the enum literals. Otherwise, double-click on the Allowable Values/Parameters field (or right-click and select the Edit Allowable Values menu option); the Edit Allowable Values dialog displays. Click on the New button, type a possible value in the text box (such as Yes or Accept), click on the Save button, and repeat the process for the next possible value (such as No or Reject).

When you have entered all possible values, close the dialog and select the appropriate response in the Result<n> column field underneath the appropriate Value<n> field for the calling condition.

For an operation, a checkbox displays in each of the Result<n> column fields; to call the operation as the response to a value of the corresponding condition, select the checkbox in the Result<n> field underneath that condition Value <n> field.

To pass parameters to the operation, double-click on the Allowable Values/Parameters field (or right-click and select the Edit Parameters menu option); the Edit Parameters dialog displays. Select the parameters and type the values into the Value text box; click on the Save button and close the dialog. You can add an operation as a Rule Action more than once, so you can call the operation with different sets of parameters.

Click on the Save button in the Rule Composer toolbar to save the values.

7 |
To add another Rule Action, right-click on the No column and select the Add Row context menu option; an empty row is added to the table. To remove a Rule Action from the table, right-click on the appropriate No field and select the Delete Row context menu option; this does not affect the original attribute or operation in the model.
