Power BI vs Data Warehouse

Hi,

In my understanding when you do Direct Query, you literally send a query to your db (tabular in this case) when user access to the contents on Power BI, thus it is not possible you add any calculation further after db returns the data;

If you do Import for your datasets, you store the data you need in the in-memory DB in Power BI cloud which allows you to do the calculations you need for those data, as they are "in" your data model.

So to satisfy your need, simply build another workbook which uses import of your datasets.

Best Regards,
