DAX: Filter on Multiple Date Columns

[Titatovenaar2]

Hi there,

I have a table ('Mutations') that has two columns with different dates ('Begindate' and 'Enddate'), and I want to be able to select a period (for instance the month April 2021) and that it then shows ALL records related to Begindate = April 2021, and Enddate= April 2021.

For that I know I need multiple steps, and the first is to integrate both columns into a single table with all values:

Mutations_Period = UNION(VALUES(Mutations[Begindate]);VALUES(Mutations[Enddate]))

Next I need 2 measures, but I only know how to do this with string values, and not with dates and especially not a date range:

Mutation_Period = FIRSTNONBLANK('Mutations_Period '[Begindate],1)

Mutation_Period_Filter = 
IF(
    ISERROR(SEARCH([Measure],FIRSTNONBLANK(Mutaties[Begindatum],1))) = FALSE() ||
    ISERROR(SEARCH([Measure],FIRSTNONBLANK(Mutaties[Einddatum],1))) = FALSE() 
    ,0,1)

Of which I put the last filter on '0' on the visual.

Any suggestions how to make this work on a date range?

Kind regards,

Igor

Hi, @Titatovenaar2 

According to your description and sample pbix file, I can roughly understand your requirement, I think you can just use this measure to apply as the visual filter of the table chart:

Flag =

VAR _selectedmonth =

    MONTH ( MAX ( 'Mutations_Period'[StartDate] ) )

RETURN

    IF (

        MONTH ( MAX ( 'Mutations'[StartDate] ) ) = _selectedmonth

            || MONTH ( MAX ( 'Mutations'[EndDate] ) ) = _selectedmonth,

        1,

        0

    )

Then go to the table chart to apply the visual filter like this:

And you can get what you want.

You can download my test pbix file below

Thank you very much!

@Titatovenaar2 ,Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

Thanks for this blog post, it's quite interesting, but I have to say that I can't easily grasp why they make the choices they do. I am experimenting with it now, but not so lucky yet.

Meanwhile, this is the file in which I have it all. Basically If I select 'April', I want 'April' from both column 'StartDate' and 'EndDate'.
