Find the first latest date and second latest date based on quarter selection dynamically

[AD_SNOW]

Team,

I have a date (which doesn't have continues dates) and quarter fields in my table (mentioned below). My quarter will go as slicer/filter and I want to find the first latest date and the second latest date based on my quarter slicer selection.

Date (DD/MM/YY)	Quarter	Flag	Comment
02/05/24	24-Q2	1	When I selected 24-Q2
18/04/24	24-Q2	2	When I selected 24-Q2
11/04/24	24-Q2
31/03/24	24-Q1	1	When I selected 24-Q1
29/03/24	24-Q1	2	When I selected 24-Q1
26/03/24	24-Q1
25/03/24	24-Q1
21/03/24	24-Q1
19/03/24	24-Q1
14/03/24	24-Q1
07/03/24	24-Q1
29/02/24	24-Q1
15/02/24	24-Q1
31/12/23	23-Q4	1	When I selected 23-Q4
14/12/23	23-Q4	2	When I selected 23-Q4

Tomorrow when data gets updated and a new date gets added (as mentioned below), my latest and second latest date flag should automatically update

Date (DD/MM/YY)	Quarter	Flag	Comment
10/05/24	24-Q2	1	New date added and the flag should show this as latest date When I selected 24-Q2
02/05/24	24-Q2	2	Automatically this should be my second latest date When I selected 24-Q2
18/04/24	24-Q2
11/04/24	24-Q2
31/03/24	24-Q1	1	When I selected 24-Q1
29/03/24	24-Q1	2	When I selected 24-Q1
26/03/24	24-Q1
25/03/24	24-Q1
21/03/24	24-Q1
19/03/24	24-Q1
14/03/24	24-Q1
07/03/24	24-Q1
29/02/24	24-Q1
15/02/24	24-Q1
31/12/23	23-Q4	1	When I selected 23-Q4
14/12/23	23-Q4	2	When I selected 23-Q4

Can someone please help me with this requirement?

Thanks!

Hello @AD_SNOW ,
Hope you are doing well.

Could you please try the below measure:
(Please know that, I have considered the QTR from the same table, if you have a date dimension table, kindly make required change in the measure)

Max QTR Date =

VAR maxdate =

CALCULATE(

    MAX('Table (2)'[Date (DD/MM/YY)]),

    ALLEXCEPT('Table (2)','Table (2)'[Quarter])

)

VAR curdate =

SELECTEDVALUE('Table (2)'[Date (DD/MM/YY)])

VAR secondmaxdate =

CALCULATE(

    MAX('Table (2)'[Date (DD/MM/YY)]),

    ALLEXCEPT('Table (2)','Table (2)'[Quarter]),

    'Table (2)'[Date (DD/MM/YY)] < maxdate

)

RETURN

IF(

    maxdate = curdate,

    1,

    IF(

        curdate = secondmaxdate,

        2,

        0

    )

)

If this solution helps, then kindly give it a kudos and mark it as a solution.

Hi @AD_SNOW 
To get the desired result you can apply an index of every date according to the quarter from PQ . 

The guide of how to get this is here :

https://radacad.com/create-row-number-for-each-group-in-power-bi-using-power-query

(Row Number By Group)

I also attached a pbix ,  you can follow my steps

From the moment that you have an index this is easy, you can create a simple dax measure for the flag :

Flag = if(max('Table'[Index]) in {1,2}, MAX('Table'[Index]), " " )

as I mentioned Pbix is attached 🙂
