Calculated column [CY_LY_Flag ] -Help needed

[sentsara]

Existing Dataset

DimTable

FactSales 

Based on FactSales.LatestMonth='Y', we need to Flag the calculated column CY_LY_Flag ="Yes" or "No" for the below two condition.

Get the LatestMonth='Y' and mark that as "Yes" 

same time Last year also needs to be flagged as "Yes"

remaining records should be "No"

Expected output: for CY_LY_Flag through Calculated Column

FactSales

BatchDate      CY_LY_Flag

03/01/2021    Yes

02/01/2021    No

02/01/2021    No

02/01/2019    No

12/01/2019    No

11/01/2019    No

03/01/2020    Yes

Please do yourself a favour and do not create unnecessary columns in fact tables. The column you're after should belong to DimTable, not your to fact table. Also, latestmonth should be moved to DimTable.

Hi @sentsara 

You can try following DAX for a calculated column

CY_LY_Flag = 

var years = {YEAR(TODAY()), YEAR(TODAY())-1 }

RETURN

IF(MONTH(FactSales[BathDate]) = MONTH(TODAY()) && YEAR(FactSales[BatchDate]) IN years,"Yes","No")

Thanks for your quick reply on this.
we need to consider based on the LatestMonth value 'Y' or 'N' as well.

Hi @sentsara ,

You can create a calculated column as below:

CY_LY_Flag = 
VAR _maxdate =
    CALCULATE ( MAX ( 'FactSales'[BatchDate] ), ALLSELECTED ( 'FactSales' ) )
RETURN
    IF (
        YEAR ( 'FactSales'[BatchDate] )
            IN { YEAR ( _maxdate ), YEAR ( _maxdate ) - 1 }
                && MONTH ( 'FactSales'[BatchDate] ) = MONTH ( _maxdate ),
        "Yes",
        "No"
    )

Best Regards
