Filter on measure

[Anonymous]

Hey everyone, 

Is there a way to count rows or distinctcount the articles where difference <0 ? Difference is a measure, based on several other measures. 

I only need one return with 3 as result. I do understand that I can't use a card visual, because you can't aggregate when you want to filter on a measure. But isn't there a workaround?

Thank you guys! @goncalogeraldes , your suggestion worked perfectly, so I will be using that measure

You can use FILTER with a measure. As it is an iterator it will perform the check for each row of the given table, e.g.

Num < 0 = COUNTROWS( FILTER('Table', [Difference] < 0) )

and you should be able to use that on a card visual as well.

Hello there @Anonymous ! Not sure if this is what you need but:

Measure = 
CALCULATE(
    COUNTROWS( 
        FILTER(
            SUMMARIZE(
                'Articles',
                'Articles'[Aggregation_criteria],
                "Diff", [Difference]
             ),
            [Difference] < 0
        )
    )
)

Hope this answer solves your problem!

Let's assume there row filter context is from the column Table[Field] and the measure is [difference]
You can try:

Count Field =
COUNTX (
    CALCULATETABLE ( VALUES ( Table[Filed] ), FILTER ( Table, [Difference] < 0 ) ),
    Table[Field]
)

It should work in a card visual
