How to get sum in Marix table subtotal for AVERAGEX?

[Anonymous]

Hi Team,

If there is any way to get subtotal result for my below example?

I do ROI impact of our promotions, but some of them can run multiple weeks and I need to find difference vs non promo/base weeks sales. This how I do Base Units sales Base Units = CALCULATE(AVERAGEX('1 Total Summary','1 Total Summary'[NON PROMO AVERAGE]),ALLSELECTED('1 Total Summary'))  

However, I would like to see sum instead of average in my subtotal result for base units/Matrix Table.

Hi,

I think I nailed it

Base Units =

VAR AvgSales = CALCULATE(AVERAGEX('1 Total Summary','1 Total Summary'[NON PROMO AVERAGE]),ALLSELECTED('1 Total Summary'))

RETURN

IF(HASONEVALUE('Calendar'[Week M]),

AvgSales,

SUMX( VALUES('Calendar'[Week M]),AvgSales))
