Sorting rows based on two columns
Hi! I am struggling with a data exercise and could use some help. I would like to return the value of column A, based on a grouped value of column B, where the value of column C is the highes...
Hi Fda,
Without seeing your dataset, I'm not sure about the exact performance. If you want to try another way (and compare the two for your particular dataset), this can also be done outside of Power Query by creating a new column with DAX:
ColumnA_IfMax = IF ( CALCULATE ( MAX ( 'Table'[ColumnC] ), ALLEXCEPT ( 'Table', 'Table'[ColumnB] ) ) = 'Table'[ColumnC], 'Table'[ColumnA], BLANK() )
Thank you for taking your time, and it looks like its working!
Is it a heavy calculation for it to make? It's running pretty slow for me, and I've got a lot of rows left?

You are a legend, that is exactly what I was looking for!
Thank you very much!
Glad to help!
