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

I have the similar issue like the topic listed below of refreshing the composite model dataset in service :

Error refreshing Composite model live connection t... - Microsoft Power BI Community

everything works fine for calculated table in desktop mode. However, when the dataset is published to the service, there will always be an SSO error message
