Incorrect Total on VAR Rolling 3 Months Forecast Projection

[JaclynPugh2022]

I have a rolling monthly forecast formula showing monthly totals, but the Grand Total is incorrect.  I cannot use SUMX(VALUES to correct this, as it will eliminate the forward projection on the forecast.  Any suggestions please?

Spend Forecast based on last 3 Mo =

VAR Spend1MonthAgo = CALCULATE([Received Spend], DATEADD('DimDate1'[Date],-1, MONTH ) )

VAR Spend2MonthsAgo = CALCULATE([Received Spend], DATEADD('DimDate1'[Date],-2, MONTH ) )

VAR Spend3MonthsAgo = CALCULATE([Received Spend], DATEADD('DimDate1'[Date],-3, MONTH ) )

RETURN DIVIDE( Spend1MonthAgo + Spend2MonthsAgo + Spend3MonthsAgo, 3 , 0 )

Result is correct subtotals, but incorrect Grand Total:   (Should be $21,627 not $32,168)

@JaclynPugh2022,

You may need to create a second measure that references the main measure. Assuming you have a dimension column like DimDate[Month] in your visual, you could try this measure:

Rolling Avg Cost 3 Mo =
SUMX ( VALUES ( DimDate[Month] ), [Spend Forecast based on last 3 Mo] )
