Aggregate of measures at different filter level - PLEASE HELP!

[snow_man]

Hi all,

I have a question related to measures in Power BI desktop. I have a table visualisation which shows a measure for each unique combination of identifiers (1, 2, & 3). (Each identifier 1 can take many values for identifier 2, which can take many values for identifier 3.)

My question is how do I aggregate the measure to find the max (or min) for a given value of identifier 1 and 2? An example is shown here of what I'm trying to achieve. The first table looks like this:

I would like a second table which evaluates the max and min at the identifier 2 level:

Any help would be much appreciated. I'm sure this must be possible with measures but this goes beyond my understanding and it's hard to articulate using a search engine.

Thanks!

Hi @snow_man ,

Please try the following methods and check if they can solve your problem:

1.Create the simple table.

2.Create the new measure to find MAX.

MaxValue = CALCULATE(MAX('Table'[Me]), ALLEXCEPT('Table','Table'[Identifier1],'Table'[Identifier2]))

3.Create the new measure to find MIN.

Minvalue = CALCULATE(MIN('Table'[Me]), ALLEXCEPT('Table','Table'[Identifier1],'Table'[Identifier2]))

4.Drag the measure into the table visual. The result is shown below.

Hi @v-jiewu-msft,

That didn't work. When I try to create the measure it says 'Column 'Measure' in table 'Table' cannot be found or may not be used in this expression.' I assume because this is a measure to begin with, not a column. 

Just to be clear, the first table in my question is a table visual, not a data table.

Hi @snow_man ,

1.Recreate the origin table and calculate the measure.

Measure = 
VAR TrueStepsCount =
CALCULATE(
    COUNTROWS('Tableorigin'),
    FILTER(
        'Tableorigin',
        'Tableorigin'[True/False] = TRUE()
    )
)
VAR TotalStepsCount = COUNTROWS(Tableorigin)

RETURN TrueStepsCount / TotalStepsCount

2.Create the new measure to filter.

MAX Measure = MAXX(ALLEXCEPT('Table','Table'[Identifier1],'Table'[Identifier2]), Tableorigin[Measure])

MIN Measure = MINX(ALLEXCEPT('Table','Table'[Identifier1],'Table'[Identifier2]), Tableorigin[Measure])

3.Drag the measures into the table visual. The result is shown below.

Hi @v-jiewu-msft ,

This would work if there were 2 tables ('Tableorigin' and 'Table') but there is only one table ('Tableorigin'). The second 'Table' is only a visual.

Is there any way around this? e.g. by creating a new table from Tableorigin?

[ryan_mayu]

is this a table visual? if yes,pls provide the raw data.

[snow_man]

Hi @ryan_mayu,

Yes the first table is a visual, with the measure being evaluated from the original data table. The raw data table looks like this:

The measure is as follows. Essentially it's giving you the proportion of 'TRUE' entries in the raw data table (which is evaluated per unique combination of identifiers 1,2&3 in the table visual).

Proportion =

VAR TrueStepsCount =
CALCULATE(
    COUNTROWS('Table'),
    FILTER(
        'Table',
        'Table'[TrueFalse] = TRUE()
    )
)
VAR TotalStepsCount = COUNTROWS(Table)

RETURN StepsCount / TotalStepsCount

I hope this helps clear things up. I look forward to your response.
