Weighted Average based on Field identifier

[bolwahnn]

Hey Guys,

How would I create a measure of a weighted average based on 2 different field values? I know how to do this in excel using SUMPRODUCT, but I'm relatively new to DAX and dont know how to do the same calculation that I would normally use in Excel.

For the below, in excel, I would use the following formula in column F:
=SUMPRODUCT(--($B$2:$B$13=B2),--($C$2:$C$13=C2),$D$2:$D$13,$E$2:$E$13/SUMIFS($D$2:$D$13,$C$2:$C$13,"="&C2,$B$2:$B$13,"="&B2))
