When you create a business object, you can override the default BO handler by specifying the CBOH keyword in the BO verb ASI. At connector runtime, the doVerbFor() method retrieves the business object ASI. If it detects the CBOH keyword, doVerbFor() invokes the custom BO handler.
The connector supports custom BO handlers on parent-level business objects only. For details about creating a custom BO handler, see the Connector Development Guide.
