In May 2017 Power BI Desktop started supporting creation of DAX measures when working in live connect mode to an external SSAS model: https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-may-fea...
This would make life so easy and make PowerBi a differentiate PowerBI from the Competition. Here's a scenario it would help me with, i am trying to setup different visuals and we prefer using a cube that way we have a powerful machine processing the cube the way we want it. Then i come across suggestions on the forum on using a calculated column to achieve a scenario X in power Bi, guess what i have to do right now? Deploy a new model :(. With this i would be able to do it out of the box!
