Task 2: Defining the eligibility rule task

You learn the steps for defining a rule task.

About this task

To define a rule task, you do the following steps:

Decide which rules the task must include.
Specify which rules to select for execution at run time (see Execution properties for rule tasks).
Specify which execution mode to apply (see Engine execution modes).
Define initial or final actions to do before or after the task runs.

You define which rules you want to run as part of the eligibility rule task, and which execution mode the rule engine uses for this rule task. You also specify a final action to do after the rule task runs.

Procedure

Select the eligibility rule task in the ruleflow diagram, and in the Properties view, click Rule Selection, and then click Edit.
In the Select Rules dialog, select the eligibility rule package. Use the arrow to move the package to the panel on the side, and then click OK.

All the rules in the eligibility rule package are now in the rule task.
In the Properties view, click Rule Task, and then select Fastpath for Algorithm if it is not already selected.
The Fastpath mode is well suited for eligibility rules because they are defined with decision tables, and the tests in rule conditions for rules generated in decision tables share the same pattern and order.
In the Properties view, click Final Action, and then select IRL and enter the following code:
```
session.displayMessage(rental.toString());
```
Defining this final action means that after all the rules in the rule task are run, the Console output displays a message that describes the details of the rental agreement.
Save your work.

Note: At the end of task 3, you fix the errors that are shown in task 2.

What to do next

In the next task of this tutorial, you define the pricing rule task, which computes rental prices for eligible customers.
