How to aggregate measure like calculated column?

[mdatmain]

I have created a new calculated column in a table with dates called Simple Projection. Simplified, the calculated column is like this and each date has that value which can be aggregated YTD.

Simple Projection = 

VAR a = 10
VAR b = 20

RETURN
    a * b

I want to be able to change the variable "a" which is not possible with calculated columns, but is possible with measures. However, when I created the measure with the same equation, it will not aggregate (as you see the total is still 1,298.56 whereas the column total is 472,676.97). I want to get the YTD for the measure, which I do it like this for the column:

Simple Projection YTD =

CALCULATE(

    SUM('Table'[Simple Projection]),

    DATESYTD( 'Invoked Function'[Date] )

)

Doing this calculation on the measure will not return anything.

Hi @mdatmain ,

You can create another new measure as below and put it on the visual to replace the previous one.

Measure =
SUMX (
    GROUPBY (
        'Invoked Function',
        'Invoked Function'[Date].[Month],
        'Invoked Function'[Date].[Day]
    ),
    [Projection Test YTD Forecast]
)

In addition, you can refer the content in the following links to get it.

You cannot aggregate measures. You need to recompute the measure for each "row"  in your visual (ie your filter context), and separately for the totals (if present in your visual). Use functions like SUMX to achieve that.
