Subtotal Column - Empty rows for other group rows

[Anonymous]

Hey everbody,

I would like to create a column that shows the occurance of a purchase on a specific adress and date. In other words, i would like to perform a distinct count of a combined Adress & date in the column Group Total. 

Usually, i would use a DISTINCT COUNT function for the combination of a DATE & Adress combined with an ALLEXCEPT statement for this combination. However, in this specific case I require the other columns to be empty. 

Adress of individual	Date of purchase	Product Group	Group Total
Homestreet 1	1-1-2021	A	1
Homestreet 1	1-1-2021	B
Homestreet 1	4-2-2021	A	1
Teststreet 2	1-2-2021	A	1
Teststreet 2	1-2-2021	C
Teststreet 3	1-2-2021	C	1

Is there anyway to perform this action in Powerbi using DAX or Powerquery?

Best regards and thanks in advance,

Ivan Pettinga

Hi @Anonymous ,

You could add an index column. Use MAX() and ALLEXCEPT() to get the max index for each group. Then if index equal to max index, then group total, else blank.
