Server Controlled Publishing using pvschange
When the Visualization server initiates a request to convert data to the Creo View format, the server uses the pvschangeworker to convert the data in the background. This Visualization server could be a Windchill server or another customized server environment.

The pvshangeworker cannot currently be used for performing Windchill Viewable Compression.
