I m working on Sharepoint powerview and its working fine before today but today i dont know it gives me below error when try to open my power view report.. This Power View report is not valid or supported by this version of Power View. It may have been saved in a newer version of Power View. If so, you may be able to open it in a newer version of Power View.

Hi Hetal, Sorry for the delay. Based on the current information, please first make sure the Power View Integration Feature is active on the SharePoint site. If it has been active, I suggest that you check whether you can create new power view reports in SharePoint and open the newly created power view reports properly. If so, it seems that the definition of the power reports in questions are modified and you need to recreate the reports. If the power view feature doesn't work any more, the issue may be related to the SQL Server Reporting Services Service Application. In this condition, I recommend that you create another SSRS Service Application and try to open the current power view reports in new service application. Reference: Create a Reporting Services Service Application Hope this helps. Regards, Mike YinMike Yin TechNet Community Support
