Overview of adding a validation rule for the validation that belongs to payment processing domain
You can add a validation rule for the validation that belongs to payment processing domain either by using the pre-defined greex xml rule or by creating a custom criteria.
Pre-defined greex ruleTo configure a simple validation with a pre-defined greex xml rule in Business Center, the business user enters the value for the required attribute in a text box.
Note: For all the validations, which are implicit and, which are detected by the system you would not be able to create validation rules. For example, CALL_FOR_AUTHORIZATION is a validation that belongs to the payment processing domain. The validation type for this ID is detected by the system. For such validation Ids, the Validation Rules tab would be disabled.
