Using measures in filter expression

ftf — Thu, 28 Apr 2022 08:29:00 GMT

Hello Community,

I'm new to PowerBi and currently wondering about how the filter in CALCULATE works.

I have a column "ColumnA" which is part of "Table1" that should be filtered and returned. Therefore, I calculate a new measure with the following expression:

newmeasure = CALCULATE(Table1[ColumnA], 'Table1'[Category] IN { "A" }, 'Table1'[Quarter] IN { 202202 })

This works fine and I'm happy with the result. However, as the quarter changes with time, I do not want to provide a fixed value but use another measure for filtering. And so I replaced the above expression with:

newmeasure = CALCULATE(Table1[ColumnA], 'Table1'[Category] IN { "A" }, 'Table1'[Quarter] IN {VALUE('Table2'[cur_quarter]) })

The measure "cur_quarter" is part of "Table2" and contains the current quarter as string. The new expression fails with the error message "A function 'PLACEHOLDER' has been used in a True/False expression that is used as a table filter expression.". From what I understand is that CALCULATE does not support measures or columns in the filter section, but to me it seems like an easy task and I see no reason why it does not work (it would work in any programming language). So far I did not find a realization that works, also trying other functions.

How can this be implemented? Do you have an idea?

I'm happy to hear your suggestions. Thank you!

ftf , QTD/Qtr based on selected date or today

QTD =
var _max = if(isfiltered('Date'),MAX( 'Date'[Date]) , today())
var _min = eomonth(_max,-1* if( mod(Month(_max),3) =0,3,Month(_max)))+1,
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))

Hi ftf,

Just the error said, you have used a TRUE/FALSE expression as a table filter expression. This is not allowed. You could refer to this official doc to learn what kind of filters can be used as the parameters of CALCULATE function: CALCULATE function (DAX) - DAX | Microsoft Docs

In addition, you need make some changes to your Measure formula.

CalculationOnFilters = CALCULATE ( SUM ( Table1[ColumnA] ), FILTER ( Table1, 'Table1'[Category] IN { "A" } && 'Table1'[Quarter] IN { VALUE ( 'Table2'[current_quarter] ) } ) ) //CALCULATE(SUM(Table1[ColumnA]),'Table1'[Category] IN { "A" },'Table1'[Quarter] IN {VALUE('Table2'[current_quarter]) })

With the sample data created, the result looks like this.

Also, attach the pbix file as reference. Hope it helps.
