Cumulative measures with SELECTEDVALUE

Hi DIACHROMA 

I think camargos88's suggestion is the best way to go. If you want to follow the approach you already had, you could do:

Measure =
VAR selection_ =
    DISTINCT ( 'Selected Sales'[Selected Sales] )
RETURN
     ( "Drive sales" IN selection_ ) * [Sum of Drive sales] + 
     ( "Online sales" IN selection_ ) * [Sum of Online sales] + 
     ( "In-Store sales" IN selection_ ) * [Sum of In-Store sales]

Please mark the question solved when done and consider giving a thumbs up if posts are helpful.
