Adobe Livecycle Forms (PDF based) with Windchill?

Can anyone help me with a use-case to understand the integration between Adobe Livecycle Form Server & Windchill for managing Smart Forms (PDF's). The requirement is to pre-populate forms with Windchill business objects attributes & Workflow variable automatically.

Attached is the screen-shot of Adobe Windchill Integration Overview.
