tell me more icon Adding Validation Logic

You can add validation logic to enforce a rule, in this case the rule that an order's ship date must occur after the date the order was placed. You will create your validation rule using the declarative validation capabilities in ADF Business Components, and define the logic using the Groovy scripting language.

To begin adding a validation rule, you will click add icon Add on the Business Rules page of the overview editor for entity objects:

Overview editor, Business Rules

Validation rules can be added in the Add Validation Rule dialog:

Add Validation Rule dialog

To specify an error message for the rule, use the Failure Handling page of the Add Validation Rule dialog:
