Windchill ESI document release output is controlled by the Windchill ESI VDB Builder. (See the VDB Builder section of this document for details.) Windchill ESI supports instance-based attributes and Windchill soft types by utilizing the services of the Windchill Adapter. Windchill ESI logic determines the appropriate objects to process. Once the objects are identified, a Windchill Adapter Query-Objects webject is invoked to obtain the relevant data from the Windchill Adapter.
