Right now we can create hierarchies in PowerPivot but I'm pretty sure I can't do it in PowerBI. I could create a Data Model in PowerPivot and use that for PowerBI I think. Is there any other work around that could be more desktop based?
Thanks! Mike
You cannot create a hierarchy in the Power BI Dashboard Preview or in Power BI. If you want this feature I would encourage you to add it to the proposed feature list here: https://support.powerbi.com/forums/265200-power-bi or vote for the item if it already exists.
You can create hierarchies in Power Pivot and deploy the model to Power BI Preview but the hierarchies are not visible.
