A question came up in the Project forums recently around how it was possible to filter the available projects for a portfolio analysis, so I thought I would post a little tip here, which from a majority of the Project Server 2010 implementations I have seen is usually forgotten or managed by business process. When you create a portfolio analysis, Project Server allows you to choose which projects you want to use as part of the analysis, out of the box, this shows you all the projects currently within the PWA instance, irrespective of their status.
