Hi Folks
I am moving data into a PowerPivot model using PowerQuery. It is possible to create calculations / derived columns in either. Is it best to create the formulas in PowerQuery or PowerPivot (with DAX). I am assuming it would be more efficient in PowerPivot due to DAX (due to the inherent efficiency of tabular models). Is this assumption correct?
I am running 64 bit Excel 2013 (Proplus).
Thanks
Steve
