Measures, columns or parameters?

[WardWijngaert]

Hello, As a beginner Power BI user I have a configuration dilemma. I have 50 columns with data (values) and want to display the same 3 calculations applied on each column. These 3 calculations are:
1: Percentage of appearance of a specific number (20) in the column
2: Percentage of appearance of another number (14) in the column
3: Sum of the 2 percentages.

I would initially program 3 specific measures for each column, but I think it can be automated, right (if not this will be 150 different measures)? How can I write general measures, without having to specify each time the specific column? I understand that working with parameters I can filter the 3 calculations by the column that suits me, right?

can you help me please?

Kind regards.

Unpivot your data. Instead of 50 columns have two - attribute and value.  Then you can write one generic measure, or maybe even solve the question through the user interface.

Great @lbendlin & @v-yanjiang-msft I tried both solutions and they work fine! Thank you very much for your help.

Hi @WardWijngaert ,

According to your description, here's my solution.

Sample:

1.Create a field parameter containing all the columns.

2.Creat three measures:

Measure =
VAR _Field =
    SWITCH (
        SELECTEDVALUE ( Parameter[Parameter Fields] ),
        "'Table'[Column1]", COUNTROWS ( FILTER ( 'Table', 'Table'[Column1] = 20 ) ),
        "'Table'[Column2]", COUNTROWS ( FILTER ( 'Table', 'Table'[Column2] = 20 ) ),
        "'Table'[Column3]", COUNTROWS ( FILTER ( 'Table', 'Table'[Column3] = 20 ) )
    )
RETURN
    DIVIDE ( _Field, COUNTROWS ( 'Table' ) )

Measure2 =
VAR _Field =
    SWITCH (
        SELECTEDVALUE ( Parameter[Parameter Fields] ),
        "'Table'[Column1]", COUNTROWS ( FILTER ( 'Table', 'Table'[Column1] = 14 ) ),
        "'Table'[Column2]", COUNTROWS ( FILTER ( 'Table', 'Table'[Column2] = 14 ) ),
        "'Table'[Column3]", COUNTROWS ( FILTER ( 'Table', 'Table'[Column3] = 14 ) )
    )
RETURN
    DIVIDE ( _Field, COUNTROWS ( 'Table' ) )

Measure3 =
[Measure] + [Measure 2]

Put the parameter in a slicer, then get the correct result:

I attach my sample below for your reference.
