Hi,
I was ready a bit older book that focuses more on Power Pivot/Power Query in Excel. It said it was quite a bit more efficient to create a custom column in Power Query, than to create a calculated column in Power Query (i.e. the table view in Power BI).
Is that still the case?
Thanks!

Hi @mmace1,
It said it was quite a bit more efficient to create a custom column in Power Query, than to create a calculated column in Power Query (i.e. the table view in Power BI).
For my understanding, the performance of calculated column and custom column are uncompariable, it depends on the requirements.They have their own advantages
We could take a look at the article below:
Calculated columns in Power BI Desktop, which explains the main difference between those two columns.
In addition, you could have a reference of this similar thread.
For further about the difference between M and Dax, you could have a good look at this article.
Best Regards,
Cherry
