    Hi esilva32

     

    It certainly looks like it would be easier to do this in the query editor. If you do need to do it in DAX, try this. Create a new calculated table:

     

    TableB = 
VAR _BaseTable =
    ADDCOLUMNS (
        GENERATE (
            DISTINCT ( TableA[Id] );
            GENERATESERIES (
                CALCULATE ( DISTINCT ( TableA[StartDate] ) );
                CALCULATE ( DISTINCT ( TableA[EndDate] ) )
            )
        );
        "TempVal"; CALCULATE ( DISTINCT ( TableA[Value] ) )
    )
VAR _Dates =
    DISTINCT ( SELECTCOLUMNS ( _BaseTable; "Date"; [Value] ) )
VAR _ResTable =
    ADDCOLUMNS (
        _Dates;
        "Total Value"; SUMX ( _BaseTable; IF ( [Value] = [Date]; [TempVal] ) )
    )
RETURN
    _ResTable

    Minor modification:

     

    TableB =
VAR _BaseTable =
    ADDCOLUMNS (
        GENERATE (
            DISTINCT ( TableA[Id] );
            GENERATESERIES (
                CALCULATE ( DISTINCT ( TableA[StartDate] ) );
                MIN ( TODAY (); CALCULATE ( DISTINCT ( TableA[EndDate] ) ) )
            )
        );
        "TempVal"; CALCULATE ( DISTINCT ( TableA[Value] ) )
    )
VAR _Dates =
    DISTINCT ( SELECTCOLUMNS ( _BaseTable; "Date"; [Value] ) )
VAR _ResTable =
    ADDCOLUMNS (
        _Dates;
        "Total Value"; SUMX ( _BaseTable; IF ( [Value] = [Date]; [TempVal] ) )
    )
RETURN
    _ResTable

Hello!
The possible result would be what is in the image below.

 

 

I need to take only a few fields where the field datahora_

 

1 is maximum.

Thanks

    Hi esilva32 

    What value do you want for each  date-Currency pair, the latest one (time)?

    Hi AlB 

     

    Yes, for each date and currency I just need to get the amount corresponding to the date and the maximum time of that date for that currency.

     

    best regards

     

    Thank you
