IF filter value does not exist, then use other values

Hi! I have a problem I have not found any solutions to.    I've made a dynamic this week vs last week metric;   Sales PW = VAR CurrentWeek = SELECTEDVALUE(Date[Week Nr]) VAR CurrentYear = SELE...

    Hi elkjoperik,

     

    There is a solution. Please refer to the file in the attachment. You need to rebuild the model. It's hard to filter the proper data in the model in which all the data is stored in one table. 

    Solution =
VAR lastweekTotal =
    CALCULATE (
        SUM ( LW_DUMMY[Revenue FY] ),
        FILTER (
            ALL ( 'Calendar' ),
            'Calendar'[WeekNum]
                = MIN ( 'Calendar'[WeekNum] ) - 1
        )
    )
RETURN
    IF (
        ISBLANK ( lastweekTotal ),
        CALCULATE (
            SUM ( LW_DUMMY[Revenue FY] ),
            FILTER (
                ALL ( 'Calendar' ),
                'Calendar'[WeekNum]
                    = MIN ( 'Calendar'[WeekNum] ) - 1
            ),
            ALL ( Segments )
        ),
        lastweekTotal
    )

Hi elkjoperik,

 

Can you share a dummy sample? Then I can write down the DAX formula.

Hi Dale,

Thanks for your reply and time.

 

I've made a dummy setup (replaced data), but the setup is identical to my orginal setup

You can find it here

 

In this dummy sample, the "Sales PW" (sales past week) is not affected by the "Segment" filter. 

But what I want is when I select the filter "segment", I want it to select the current SKUs, but ignore the current segment when it comes to find the revenue last week from the segment.

      WOW! That worked epic!

       

      Just one thing, I also have a YEAR filter, how would I integrate that into this formula ? Because now the formula gets the right week, but it takes sales from all years and not selected year

        Hi Anonymous,

         

        I'm glad it helps. Please try this upgraded formula that will respond to the year slicer. You can download the file from https://1drv.ms/u/s!ArTqPk2pu-BkhBLE5poCyLQsDBnQ.

         

        Solution 2 =
VAR lastweekTotal =
    CALCULATE (
        SUM ( LW_DUMMY[Revenue FY] ),
        FILTER (
            ALL ( 'Calendar'[WeekNum] ),
            'Calendar'[WeekNum]
                = MIN ( 'Calendar'[WeekNum] ) - 1
        )
    )
RETURN
    IF (
        ISBLANK ( lastweekTotal ),
        CALCULATE (
            SUM ( LW_DUMMY[Revenue FY] ),
            FILTER (
                ALL ( 'Calendar'[WeekNum] ),
                'Calendar'[WeekNum]
                    = MIN ( 'Calendar'[WeekNum] ) - 1
            ),
            ALL ( Segments )
        ),
        lastweekTotal
    )
