I'm creating a PerformancePoint (henceforth PP) Dashboard that contains a web report to be deployed to the a SharePoint web application that I had created. I followed the instruction in the link below.
Deploy a PerformancePoint dashboard to a SharePoint site
In summary, following the instructions in the link, I published the Dashboard to the PP site. Then, I added my account in PP as Creator in the Application level, Editor in both the Dashboard and the Web Report. In the SharePoint site, I added my account under Contributor. I even added the PerformancePointDefault.master just to be sure.
Now, when I deploy my Dashboard to a Report Library, I was able deploy the folder for the Dashboard, but not the Dashboard Page file.
I googled for this, but I could not find any article helpful.
UPDATE 2009-09-30:
I was able to resolve the issue by creating another site collection. Maybe the first site collection is messed up.
Best Answer
I had the EXACT same problem. I was about to take the best advice I could find and delete my site collection and create a new one from scratch, but by the grace of God, I had one final thought.
In our case, the site created was originally http://ServerName but we later added a host header (i.e. http://BiSite). I had been deploying the dashboard using the host header the entire time, so I decided to try using the original name of the site using the server name and viola, the dashboard finally deployed correctly, pages and all.
