Use the Transformation Business Service textbox to select the business service that performs transformations for messages using this subnet.
Provided you have a CASP broker integration product installed, the transformation business service transforms messages in one format to the format that is acceptable to the next business component on the route. The Message List tab is where you define which message formats are acceptable to a particular business component or client.
For more information on message transformation, refer to the documentation for the broker integration product used at your site.
