Self Service BI and Licensing

Thanks for your reply, Much Appreciated. 

I understand with Premium capacity we can roll out to wider audience as App with View only permission. In the App release process, we have the control to let end user to "Reshare" and "Build" new report from the dataset. 

For the Non-Pro-License Users to build new report from the Power BI dataset, does it have to be only Power BI Desktop or they can create  new report in the Power BI Service? Do they need Pro license to save the new report in Workspace ?

By introducing Azure Analysis Service to build live reports , can end users without Pro-License use Power BI Service to build the self service report. In old days end user can connect to SSAS from Excel and build pivoted reports and charts, i am wondering if they same can be achived using Power BI Service. 

thanks
