Background
Out-of-the-box Windchill Visualization Services can create representations three ways. They are by manual creation from the Windchill UI, the check-in of a Representable (an object that can have Representations; i.e. EPMDocument, WTPart, WTDocument), and by a schedule job. This document will help explain how to initiate publishing in other ways such as custom code for workflows, from a custom UI, etc.
This topic also explains how to customize the creation of representations from such existing mechanisms like the check-in of a Representable or by a schedule job. Unlike manual creation, there is no out-of-the-box way to specify special configuration specifications for publishing, or provide business specific information you may want to capture in the name or description of the Representation.
