    Hi all,

     

    I managed to solve it through af combination of the suggestions posted in the thread.

    Thanks to everyone for inputs!

     

    The solution for the time of controls was:

    FirstControl =
    MINX (
        TOPN (
            1, 
            'QualityControl', 
            'QualityControl'[CheckedDateTime], 
            DESC 
        ), 
        'QualityControl'[CheckedDateTime] 
    )

SecondControl = 
    MINX (
        TOPN (
            2, 
            'QualityControl', 
            'QualityControl'[CheckedDateTime], 
            DESC 
        ), 
        'QualityControl'[CheckedDateTime] 
    )

     

    As I actually needed the five latest times of control I just increased the TOPN value for each measure.

Hi johnt75 

Thanks for your response!
I'm unable to use the INDEX function. I think it's due to the DirectQuery connection.
I have the same issue sometimes with the CALCULATE function.

Are you running the December 2022 version of Power BI Desktop? If not, try updating to the latest version. The INDEX function was only introduced in November or December I think.

    Sorry for my late response.
    It took some time to get Power BI Desktop updated as I'm not allowed to do it myself.

     

    I've tried to use your suggestion but get the error:

    "INDEX Relation paramter may have duplicate rows. That is not allowed."

      For the first QC date you could simply use MIN('Quality Control'[Checked datetime]), for the 2nd you can try

      Second QC =
VAR Top2 =
    TOPN ( 2, 'Quality Control', 'Quality Control'[Checked datetime], ASC )
RETURN
    MINX ( Top2, 'Quality Control'[Checked datetime] )

        I still have issues.

        Unfortunately I'm not able to share the data as a DirectQuery connection, but I've made some sample data in Excel. Both Excel and PBIX files are attached.

        I've tried to create both of the measures you've suggested.
