Help with DAX Columm

[rod_puente]

Dear All

Please I need help with a function in DAX as a column and not as a measure that shows the sum of the last 3 months. I have this example and the yellow column should be the result of a column function by DAX:

Regards

Ultimos 3 Meses = 
VAR _MaxDate = 
CALCULATE(
    MAX( 'Table'[Date] ),
    ALLEXCEPT( 'Table', 'Table'[Product])
) 
VAR _Result = 
CALCULATE(
    SUM( 'Table'[Value] ),
    DATESINPERIOD( 'Table'[Date], _MaxDate,-3,MONTH )
    ,ALLEXCEPT( 'Table','Table'[Product] )
)
 
RETURN
_Result

Hi @rod_puente 

You can try this

Last 3 Months Sales = 
VAR _MaxDate = CALCULATE(MAX('Table'[Fecha]), ALLEXCEPT('Table', 'Table'[Producto]))

RETURN
CALCULATE (
    SUM('Table'[Valor]),
    DATESINPERIOD('Table'[Fecha], _MaxDate, -3, MONTH),
    ALLEXCEPT('Table', 'Table'[Producto])
)

Hope this helps

Joe

Hello, I hope I understood your request correctly

Sum3LastMonths =
VAR CurrentDate = 'YourTable'[Fecha]
RETURN
CALCULATE(
SUM('YourTable'[Valor]),
DATESINPERIOD('YourTable'[Fecha], CurrentDate, -3, MONTH)
)
