Webservice implementation can be changed to fetch additional cost types and quantity information. This service can either be hosted by the ESI EAI software components, or in a legacy system provided it uses the same WSDL interface. Refer to the Windchill Enterprise Systems Integration Open Application Programming Interface Guide for more details.

ESI services may be configured to use a customized web service by setting the distribution target attribute Web Service Definition URL. This attribute has a default value of http://localhost:6666/ProcessDefinitions/DataProcessing/SOAPServer?wsdl, which may be modified to the URL corresponding to the customized web service.
