For the design guide on how to model logic see Decision Management guide.
A business rule applies logic. It is specified by using an IF-THEN construction.
A business rule derives one decision. If you wish to derive more than one decision a decision table is the best option. Business rules are used when assessing requests, e.g. a mortgage request. A business rules is best applied when:
Reasoning about multiple instances is required
Uniformity is important
Insight into management rules is important
Flexibility and maintainability of the management rules are important
| Property | Description |
|---|---|
| If | Use the expression editor to create the condition of the business rule. When this condition is met the specified value is assigned to the action. |
| Then | Choose any attribute to create the action of the business rule. |
| Is | Use the expression editor to assign a value to the action attribute (THEN) if the condition is met (IF). This can be a plain value or an expression that evaluates to a value of the same basetype as the action attribute. |
| Justification | The Justification contains an explanation behind the logic that is used in the business rule. Select the asset from the drop down list. |
It is not possible to use a business rule to clear an attribute value, contrary to using a decision table. |
