Hi josemave,

Simply put, Infoview is the portal where ALL of your content …deski, webi, crystal etc… can be viewed by whom ever with proper authorization. If your Bussiness Objects was installed correctly, there is no seprarte connection that you need to establish to view a webi doc once it has been exported properly to your CMS: the server where your documents reside among other things…i.e. what your viewing via Infoview.
As for your error, this should help:
