Rolling Sum - Last period

[amirghaderi]

I have a rolling sum measure as below which measures 3 weeks rolling of column "periodic:Earned". I want another measure which only calculate the the last period rolling sum and everything else to be zero. For example, in the below table, only shows the rolling sum for 16-Apr-21 (26.07) and all previous periods to be zero.

Can somebody help?

Hi, @amirghaderi 

Please check the below picture and the sample pbix file's link down below.

All measures are in the sample pbix file.

Only show last period rolling total =

VAR lastdateinperiod =

CALCULATE ( MAX ( Qty[Date] ), ALL ( Qty ) )

RETURN

CALCULATE (

[Qty total 21days rolling],

KEEPFILTERS ( Dates[Date] = lastdateinperiod )

)

Not sure why "Qty total 21 days rolling comes blank.

Hi, @amirghaderi 

I think, in your table visualization, the Dates[Date] is not used. Instead, [Date to 2] is used.

Hi, @amirghaderi 

I am not sure hour your whole data model looks like, but the simplest way (in my opinion) is, adding an IF condition something like below.

Qty total 21days rolling =
if ( not isblank( [Qty total]), your measure......)
