Distinct Sum by

[Anonymous]

Hello Everyone, 

I have a report that I am trying to sum invoice totals by the distinct invoice number for that particular purchase order and supplier.  For some reason I am unable to get the correct answer.  Below is some sample data and what I expect the output to look like. 

I tried using the following formula but it is not working as I thought it would - 

CALCULATE(SUM('Source Data'[ Invoice Total]), DISTINCT('Source Data'[ Inv Number]))

Any help would be reatly appreaciated. I am a Power BI newbie so I am not 100% how to move forward from here.

Thanks!

@Anonymous try this measure

Distinct Sum = 
SUMX ( VALUES ( Table[Invoice Number] ), CALCULATE ( MAX ( Table[Invoice Amount] ) ) )
