Create calculated columns when using SSAS live connect

[WillT]

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-feature-summary/ Vote on this idea if you want support for calculated columns in this mode as well!

Yes we need it and will surely do much help rather going back to cubes. Thanks.

'Definitely a requirement. Part of a leading manufacturing/automation organization, being agile on our feet with data is extremely important. +100 from my end.

This is not a practical request. A DAX Measure is metadata, and can be passed in at query time. This allows you to creat DAX measures in Power BI and execute them in Analysis Services. A calculated column is a materialized data element evaluated at model process time. Adding the ability for users to add these in Power BI is dangerous because you are essentially adding model development. Calculated columns are generally An anti pattern in enterprise models, because they consume memory and logic that uses them is almost always better placed in ETL or a measure definition. Do NOT do this.

I would also like to be able to combine data sources when one of them is a live connection to SSAS. For example, combine fields from an Excel spreadsheet with a related SSAS data source. There is probably a separate suggestion out there already for this but I haven't found it yet... If anyone can point me to one please do so I can vote on it rather than duplicating!

This is definitely needed for both Tabular and Multidimensional. The lack of this is one of the key arguments for investing in other solutions than PowerBI.

Yes, me too. I want to adding calculated columns to reports which connecting Power BI Services dataset. For adding date columns from date/time column, For grouping 1-5, 6-10, 11-15, ... value columns from 1,2,3,4,5, ... columns. I like the feature to adding measures to reports which connecting Power BI Services. So, I hope the feature to adding calculated columns, too.

Yes we need this. Critical element to make Power BI useful

[nicky_hopkins]

The facility to create calculated columns in multidimensional mode is essential to any BI tool whether using Multidimensional or Tabular modes.

[eric_veiluva]

Yes, it will be a good improvement.

The fact that we can't do this now is one of the main reason our end users are slow to warm up to the idea of using power bi. Please please please add this functionality.
