Share your thoughts on DirectQuery for Power BI datasets and Azure Analysis Services (preview)

tessahurr I tired it this morning and I got the following error meassage. 

"cannot load model we couldn't connect to your directquery data source or internal model. Double Check That your server and databasenames are correct, and that you have permissions to access them OLE DB or ODBC error."

I continued and added my 2nd source (SQL) to the model. The Liveconnection model converted to a local model, but all my visuals shows now a error with:

"Couldn't load the data for this visual" - OLE DB or ODBC error. 

The Preview Option is activated. Is there anyone who solved this?

Best Regards
Manuel
