Project Server 2010 and SharePoint

Unlike predecessor versions, which could work with SharePoint Server but did not rely on it, Project Server 2010 requires SharePoint Server for some of its functionality. For example, Project Server 2010 uses Excel Services and PerformancePoint Services—two SharePoint Enterprise CAL—level features—for reporting. To mitigate the cost of the additional SharePoint licenses, Microsoft is offering special accommodations for customers who have Software Assurance (SA) subscriptions for their Project Server—related licenses as of Apr. 30, 2010.

Project Server licenses. Customers with an existing Project Server license and an SA subscription receive one complimentary SharePoint Server 2010 license (in addition to the right to upgrade to Project Server 2010). However, after the SA subscription on their Project license expires, the complimentary SharePoint Server 2010 license is no longer covered by SA and customers who want to continue their eligibility for SA upgrade rights will need to begin paying for a SharePoint Server SA subscription as well as for their Project Server SA subscription.
