Use Parameter to Slice Aggregate Measure?

Anonymous — Wed, 21 Feb 2024 21:44:17 GMT

Hello all -

Based off the below dataset, I have summed the 'daysonjob' column on my dashboard. Is there a way to filter or slice that aggregation based off a parameter within DAX?

For example - If a parameter is selected as "all", I would like to see the sum of the entire column 'daysonjob'. If the parameter is selected as 'remove days off site,' I would like to see the sum of 'daysonjob' where 'laboronsite' = 'Y'.

Essentially, I want the user to be able to select 'Days On Job' as all days the job has been active or only days where labor was actually on site.

Is this possible? From my memory, this can be easily achieved in Tableau, but I can't seem to figure out how to write a DAX measure with parameters.

Thanks in advance,

yes, prepare separate measures and then add them all to the same field parameter.

Hi Anonymous

Here are two methods:

The first one is to use the field parameter:

I create a set of sample data:

Then add two measure:

N = CALCULATE ( SUM ( 'Table (2)'[daysonjob] ), FILTER ( ALLSELECTED ( 'Table (2)' ), 'Table (2)'[laboronsite] = "N" ) )

Y = CALCULATE ( SUM ( 'Table (2)'[daysonjob] ), FILTER ( ALLSELECTED ( 'Table (2)' ), 'Table (2)'[laboronsite] = "Y" ) )

Add the two measure as parameter:

The result is as follow:

The second method:

Create a new table:

Table = {"Y","N"}

Then add a measure:

Measure = VAR _Newvalue = SELECTEDVALUE('Table'[Value]) VAR _labor = SWITCH( _Newvalue, "Y","Y", "N","N" ) RETURN CALCULATE ( SUM ( 'Table (2)'[daysonjob] ), FILTER ( ALLSELECTED ( 'Table (2)' ), 'Table (2)'[laboronsite] = _labor ) )

Create a slicer with table[value] and a card with the measure:

The result:

This is helpful, thank you! One more thing I did not explain. I need the aggregate measure to also act as the denominator in an equation. It appears I am not able to reference the Parameter in a DAX statement as a denominator. I created the below measure, and it seems to work as the denominator in a DAX statement.

DOJ_PARAMETER_VALUE = VAR __SelectedValue = SELECTCOLUMNS ( SUMMARIZE ( 'Days On Job Parameter', 'Days On Job Parameter'[Days On Job Parameter], 'Days On Job Parameter'[Days On Job Parameter Fields] ), 'Days On Job Parameter'[Days On Job Parameter] ) RETURN IF ( COUNTROWS ( __SelectedValue ) = 1, __SelectedValue )
