Calculate Gross Sales Variance Based on Selected filtered Dates

[Anonymous]

Hello,

I'm new with DAX and had a question about how to calculate the variance of gross sales between two months. The two months selections are to going to be filters/slicers.

I have three simplete tables.

Data table looks like this.

Forecast Date Measure Amount
6/1/2020 Gross Sales 1,000
7/1/2020 Gross Sales 2,000
8/1/2020 Gross Sales 3,000
9/1/2020 Gross Sales 2,000
10/1/2020 Gross Sales 1,500
11/1/2020 Gross Sales 500
12/1/2020 Gross Sales 3,250

I want to write a formulate that calculates the difference in gross sales (CM Gross Sales - PM Gross Sales), however the filter for the forecast dates needs to come from the filtered selection.

Something like this.

Gross Sales Var = calculate(sum([Amount]),Filter(XXCM SelectionXX) - calculate(sum([Amount]),Filter(XXPM SelectionXX)

The XXSelection needs to be the months selected in the filters.

Any help?

Thanks

Hi  @Anonymous ,

Here are the steps you can follow：

1. Create measure.

Measure 2 =
var _max=MAX('Table'[Forecast Date])
var _min=MIN('Table'[Forecast Date])
return CALCULATE(SUM('Table'[Amount]),FILTER('Table','Table'[Forecast Date]=_max))-CALCULATE(SUM('Table'[Amount]),FILTER('Table','Table'[Forecast Date]=_min))

2. Result.

You can downloaded PBIX file from here.

@Anonymous,

Try this measure. Each slicer is based on its corresponding table (e.g., CM Forecast Date slicer is based on 

CMFCST[CM Forecast Date]). No relationships exist between the three tables.

Gross Sales Var = 
VAR vCMDate =
    SELECTEDVALUE ( CMFCST[CM Forecast Date] )
VAR vPMDate =
    SELECTEDVALUE ( PMFCST[PM Forecast Date] )
VAR vCMAmount =
    CALCULATE ( SUM ( Data[Amount] ), Data[Forecast Date] = vCMDate )
VAR vPMAmount =
    CALCULATE ( SUM ( Data[Amount] ), Data[Forecast Date] = vPMDate )
VAR vResult = vCMAmount - vPMAmount
RETURN
    vResult
