get last value from Date

[Devilstar]

Hello,

i am trying to get the last value from a date. This value should be use for the month before which are null.

The initial situation looks like that:

After a DAX-Function the result should look like this:

About help or solution suggestions, I would be very happy!

Thanks,

Looks like a good candidate for Fill Up in the Power Query Editor(Transform).

It only works for null entries, remember so you may have to use Replace first.

thank you for your suggestion! With the function Fill Up it works (with import from SAP BW).

But i want to use in the next time direct query (on SAP BW), so i have to solve it with a function.

On this topic there is nearly the same problem case:

https://community.powerbi.com/t5/Desktop/Fill-blanks-with-previous-value/m-p/492572#M229548

i change there solotion for my case:

Value2 = 
VAR CurrentCar = 'Table'[Car]
VAR CurrentDate = 'Table'[Month]
VAR CurrentRegion = 'Table'[region]
VAR LastDateWithValue =
    CALCULATE (
        MAX ( 'Table'[Month] );
        FILTER (
            'Table';
            'Table'[Value] <> BLANK ()
                && 'Table'[Car] = CurrentCar
                && 'Table'[Month] = CurrentDate
                && 'Table'[region] = CurrentRegion
        )
    )
Return
    CALCULATE (
        LASTNONBLANK('Table'[Value];'Table'[Value]);
        FILTER (
            'Table';
            'Table'[Car] = CurrentCar
                && 'Table'[Month] > LastDateWithValue
                && 'Table'[region] = CurrentRegion
                      )
    )

Now it looks like that:

Unfortunately, it is not the solution yet....

if would like to have a formula like this:

value3 = if('Table'[Value]=BLANK();"get last Value";"nothing")

Have anyone a solution?

Thanks,

alex

HI, @Devilstar

You could try this formula to add a column as below:

Value 2 = 
VAR CurrentCar = 'Table'[Car]
VAR CurrentDate = 'Table'[Month]
VAR CurrentRegion = 'Table'[region]
VAR LastDateWithValue =
    IF (
        ISBLANK ( 'Table'[Value] ) = FALSE (),
        'Table'[month],
        CALCULATE (
            MIN ( 'Table'[month] ),
            FILTER (
                'Table',
                'Table'[car] = EARLIER ( 'Table'[car] )
                    && 'Table'[region] = EARLIER ( 'Table'[region] )
                    &&'Table'[month]>=EARLIER('Table'[month])
                    && ISBLANK ( 'Table'[Value] ) = FALSE ()
            )
        )
    )
RETURN
    VAR A =
        CALCULATE (
            LASTNONBLANK(  'Table'[Value], 'Table'[Value] ),
            FILTER (
                'Table',
                'Table'[Car] = CurrentCar
                    &&  'Table'[Month]  = LastDateWithValue
                    && 'Table'[region] = CurrentRegion
            )
        )
    RETURN
        IF ( ISBLANK ( 'Table'[Value] ), A, 'Table'[Value] )

Result:

Hi @Devilstar,

You can use the below DAX to create the custom column.

Value2 = 
VAR CurrentCar = 'Table'[Car]
VAR CurrentDate = 'Table'[Month]
VAR CurrentRegion = 'Table'[region]
VAR _LastDateWithValue =
    CALCULATE (
        MIN ( 'Table'[Month] ),
        FILTER (
            'Table',
            'Table'[Value] <> BLANK ()
                 && 'Table'[Car] = CurrentCar
                && 'Table'[Month] > CurrentDate
                && 'Table'[region] = CurrentRegion
        )
    )
var _result=   IF(ISBLANK('Table'[Value]), CALCULATE (
        FIRSTNONBLANK('Table'[Value],1),
        FILTER (
            'Table',
            'Table'[Car] = CurrentCar
                && 'Table'[Month] = _LastDateWithValue
                && 'Table'[region] = CurrentRegion
                      )
    ),'Table'[Value])
Return
_result

Below is the result I have got from the above expression.
