Facing the same issue of 'Query System Error' when Power BI tries to connect SSAS MD model using Live connection. Frown traces are also the same. Applied SP 2 with CU10 for SQL Server 2014 (Latest updates) but still getting the same error. Any clue on probable solution on SSAS / Power BI end?
We are facing the same issue. Looks like Microsoft is not having any solution to this. We have enterprise version, CU8, SQL Server 2014, Power BI Pro and still gets the error. SSAS service restart used to be a work around till now, but now that is also not working out. Please suggest.
Can anyone from Microsoft take a look specifically at the PBI and cube level and sugget? Its a show stopper for us as client is unable to use the report.
