Compare two dates to create flag

[prasadhebbar315]

Hello all,

I am looking at a solution to identify if there exists ML_date before Escalation_Date by each Serial number.

In the below table, for Serial_Number:100 , Escalation_Date is 3/2/2023 but the minimum ML_Date is 3/3/2023 which is after Escalation Date and hence "No" in the last coulmn.

For Serial_Number:200 , Escalation_Date is 4/1/2023 but the minimum ML_Date is 4/1/2023 which is on or before Escalation Date and hence "Yes". 

Serial_Number	Escalation_Date	ML_Date	Data_Available_On_Before_Escalation
100	3/2/2023	3/5/2023	No
100	3/2/2023	3/4/2023	No
100	3/2/2023	3/3/2023	No
200	4/1/2023	4/2/2023	Yes
200	4/1/2023	4/1/2023	Yes
300	4/11/2023	4/8/2023	Yes
300	4/11/2023	4/7/2023	Yes
300	4/11/2023	4/6/2023	Yes
400	5/1/2023	5/4/2023	No
400	5/1/2023	5/3/2023	No
400	5/1/2023	5/2/2023	No

Hi,

try a calculated column with this DAX:

Column = var _mindate = CALCULATE(min('Table'[ML_Date]),ALLEXCEPT('Table','Table'[Serial_Number]))

return

if ('Table'[Escalation_Date] < _mindate, "No", "Yes")

If I answered your question, please mark my post as solution, Appreciate your Kudos 👍

Thanks @serpiva64 @DOLEARY85 both solutions have worked.

Hi, 

you can add a calculated column

Column =

VAR currser = 'Table'[Serial_Number]

VAR minMLdate = CALCULATE( MIN('Table'[ML_Date]), FILTER('Table', 'Table'[Serial_Number]=currser ))

RETURN

IF( 'Table'[Escalation_Date] >= minMLdate, "yes", "no" )
