Marking latest date within selected date range

[GKJARC]

Hi everyone,

In a Power BI report I need to mark Active participants as 1, based on the latest ParticipationDate labeled Green, within the selected date range.
With the date slicer ranging from 1-1-2020 to 31-8-2020, the outcome should be like this:

ID	ParticipationDate	Green/Red	Latest green	Active participant Y/N
1	3-2-2020	Green	12-2-2020	0
1	12-2-2020	Green	12-2-2020	1
1	16-4-2020	Red	12-2-2020	0
2	1-5-2020	Green	1-5-2020	1
2	9-8-2020	Red	1-5-2020	0
2	2-6-2021	Green	1-5-2020	0

There are also slicers on the report page for Table1 that need to remain usable:

Measure used for Latest green:

Latest green =

MAXX(

    FILTER( ALL('Table1'),

        [ID]= MAX([ID]) &&

        Table1[Green/Red] = "Green" &&

        Table1[ParticipationDate] >= MIN('Date'[Date]) && Table1[ParticipationDate] <= MAX('Date'[Date])),

        Table1[ParticipationDate])


Data model in my sample report:

I created this calculated column but it doesn't do the trick, because it ignores the date slicer:

Active participant Y/N =

   IF ( [Latest green] = Table1[ParticipationDate] , 1,

   IF ( ISBLANK(  [Latest green]) , 0

   ,0  ))

What would be the correct way to achieve the desired result?

Thank you for your replies, much appreciated!@amitchandak was right and a measure needed to be used:

Active participant Y/N =

     IF ( HASONEVALUE ( Table1 [ID] ),

            IF ( [Latest green] = SUM ( Table1 [ParticipationDate] ) ,1 , 0

            )
     )

The column Table1[ParticipationDate] needs to be set to data type Date or DateTime.

Hi @GKJARC ,

Check whether the ParticipateDate field is the correct date type. After modification, can you get the correct result? I created a similar data model. After importing, the text type is displayed, and the date cannot be judged directly on this field. Is it possible to provide the correct data model (delete sensitive information), I will answer you as soon as possible.

Looking forward to your reply.

Best Regards,
Henry

@GKJARC , a calculated column will not take the slicer value. You have to create a measure
