Had a question come up about how to use a SharePoint document library within PPS.   Use the following steps to create it.

1. Open SharePoint Designer and open your SPS site
2. Create an ASP.NET page
3. Drag and drop your document library onto the page
4. Attach the SPS stylesheet so it looks pretty
5. Save it to the document library on the site
6. In PPS Designer, create a Web Page Report view and link to that page URL in the SPS document library
7. Drag and drop onto your dashboard and publish

 Let me know if you have any questions
