Modified DAX Formula for Categorizing based on Date of Test Completion

[Darko_Giac]

Hi all,

I'm looking for a slight modification to a question I had earlier which I can't quite get to work.

I'm looking to create a calculated columns using DAX that will categorize students into one of 6 categories based on when they completed a test.

I would have to take into consideration the date as well as time (so if a student completed an array of tests on the same date, the time would determine into which category they fell)

I have attached a screenshot of sample data as well as the desired result which will (hopefully) be a clearer reference.

Any suggestions would be greatly appreciated

Try this calculated Column

Notes =
VAR FirstClass =
    MINX (
        TOPN (
            1,
            FILTER ( Table1, [ParticipantID] = EARLIER ( [ParticipantID] ) ),
            [Assessment_end_date_time], ASC
        ),
        [Class]
    )
VAR SecondClass =
    MINX (
        TOPN (
            1,
            FILTER (
                Table1,
                [ParticipantID] = EARLIER ( [ParticipantID] )
                    && [Class] <> FirstClass
            ),
            [Assessment_end_date_time], ASC
        ),
        [Class]
    )
RETURN
    "Completed " & SecondClass
        & " after "
        & FirstClass

Thanks for this! 

How would I modify the syntax to categorize by groups instead of "Completed X after X".

For example, is there a way to change the label to "Group 1" for those that completed Q after V, "Group 2" for those that completed "NV after V", etc...

Thank you!

Hi @Darko_Giac

My apologies for late reply

After creating above column, you can create another column as follows to get GROUPINGS.

Please see the Power Pivot Model in attached Excel File

Group =
"Group " & RANKX ( Table1, [Notes],, DESC, DENSE )

Perfect, thank you!
