AX 2012 - Report in Visual Studio Error:Unable to open Also the icon of report is missing in Visual Studio

Hi all,

I am having a strange issue ,the report icon in ax 2012 ssrs report in visual studio is not displaying.(attached screenshot).

Also when I click on that report its giving me the error 

Unable to open '\SSRS Reports\Reports\Cheque_US' in Model Editor. Set the Build Action property for '\SSRS Reports\Reports\Cheque_US' to CompileModel, and be sure to open the file from within a Dynamics AX project.

This error exists for all the reports.

Thanks,

Vicky
