Project Server 2013 Sample reports

Hi All,

I have installed Project Server 2013 and configured the sample report using the steps provided in the below link.

http://technet.microsoft.com/en-us/library/ee662106.aspx

All the reports are working fine except the overview reports (Project Overview, Resource Overview, and Project Overview Dashboard). The reports are not showing any data, if we try to refresh it is showing the below error.

When we try to add the files by selecting the right side field list we are getting the below error.

Whether I am missing any configuration, please help me to resolve the issue.

Thanks in advance.

Thanks in advance, Arun
