I am working on Power BI with a SSAS instance. I am using a direct connection to browse the data. I need to build custom measures and columns to create a dashboard, but the buttons are greyed out and the right-click menu on a table does not show 'New mesure' or 'New column'.
Obviously I am missing something, any idea what?
No you can't create measure or column if you are connected to SSAS
Question: If I created a live connection, can I edit the model or query in Power BI Desktop?
Answer: No. All of the query and modeling features in Power BI Desktop are disabled when exploring live data.
