one top row data

It's a little hard to explain, I need to use the same formula in a single dax formula, the one in the top row. I'm trying to power the "Exponential Smoothing" column in the excel below. Is something ...

Hi ,

 

 

 

Exponential_1 =
([Input2Values]*[Measure Last Period]) + ([Input2Values] * [Measure Last Period](Wrong) )
 
20200301 = (0,5*633.973) + ( 0,5*4.076.361 ) = 2.355.167 must
20200401 = (0,5*766.859) + ( 0,5*2.355.167 )= 1.561.013 must

    Hi ForzaMami ,

    You can create a measure as below to get it:

    Exponential_1 =
VAR _curym =
    SELECTEDVALUE ( 'Table'[Year_Month] )
VAR _selalpha =
    SELECTEDVALUE ( 'Table'[Alpha] )
RETURN
    _selalpha
        * SUMX (
            FILTER ( ALLSELECTED ( 'Table' ), 'Table'[Year_Month] <= _curym ),
            [Measure Last Period]
        )

    If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. Thank you.

        Hi ForzaMami ，

        According to the information inside the latest reply you gave, the result of the current item is calculated based on the result after the previous item is calculated. And as tamerj1 said, it involves recursive calculation, I'm afraid it's difficult to achieve what you need with DAX...
