I can't seem to figure out how to change what SSAS server/instance that is used to build the cubes for Power View items uploaded to SharePoint. I tried changed the trusted servers listed in the Excel Services service application but if I remove the original SSAS server (which of course is a test server, not to be used for production) and have only the prod SSAS instance listed the reports fail to load with the generic 400 error. Is there another setting that I'm missing?
Thanks,
Kyle
