    Hi andrewsk

     

    As a NEW TABLE, try this

     

    New Table=
FILTER (
    'Product Data',
    'Product Data'[ProductCategory] = "Mountain Bikes"
        && CALCULATE ( AVERAGE ( 'Sales Data'[Unit Price] ) > 1000 )
)


    FILTER function is an interator. All ITERATORs (like FILTER,SUMX,MAXX etc) work in folllowing fashion.
    1) They create a ROW context on the TABLE received as first argument

    2) They evaluate the second expression for each ROW of that TABLE


    However FILTER only provides ROW context and not the FILTER context.
    Calculate transforms that row context into filter context allowing you to work with relationships

Guys, is there a way to do this so the filters are treated like a logical OR, not a logical AND?

Just got it... 

CALCULATETABLE (
    'Product Data',
    FILTER (CROSSJOIN('Product Data', 'Sales Data'), 'Product Data'[ProductCategory] = "Mountain Bikes" || 'Sales Data'[Unit Price] > 1000 )
)
