Weekly Sales - Last week not null sales

Hi Everyone,

 

we have a date dimension and sales fact table. we have to display sales by week.

 

dropdown slicer: week(feb 4 - feb 10).

 

when we display sales, if the selected week does not have sales, we should consider the previous week, till the week which is having the sales.

 

How do we do that using DAX?

Hi @LivioLanzo  and @v-cherch-msft 

 

plz find the sample dataset and pbix files.

 

https://github.com/bodempudi/CodeSnippets/blob/master/PowerBI/Demos/DataSet.xlsx

 

https://github.com/bodempudi/CodeSnippets/blob/master/PowerBI/Demos/sample_pbix_file.pbix

 

i have the PBIX file too, please select the week date range and see the stacked chart. when we have sales for a particular week, we should consider the previous week, which is having sales.

 

Thanks..

Hi @powerbidevelope 

 

You may try below measure.Attached the file for your reference.

Measure = 
VAR LastWeek_notnullsales =
    IF (
        [SUM_Sales] = BLANK (),
        MAXX (
            FILTER ( ALL ( Dimdate ), Dimdate[WeekOfYear] < MAX ( Dimdate[WeekOfYear] ) ),
            [WeekIndex]
        ),
        MAX ( Dimdate[WeekOfYear] )
    )
RETURN
    CALCULATE (
        [SUM_Sales],
        FILTER ( ALL ( Dimdate ), Dimdate[WeekOfYear] = LastWeek_notnullsales )
    )

Re: Weekly Sales - Last week not null sales

Hi @v-cherch-msft 

 

it is not working when user selects multiple weeks.

 

in our example, if users selects Feb 17-Feb 23 and Feb 24 - Feb 28. it should display Feb 17- Feb 23.

 

It is not working, it is displaying blank report.

 

Thanks..

Re: Weekly Sales - Last week not null sales

after modifying the expression as below it is working fine..

 


Measure =
var week=max(Dimdate[WeekOfYear])
VAR LastWeek_notnullsales =
IF (
(CALCULATE([SUM_Sales],Dimdate[WeekOfYear]=week) = BLANK ()),
MAXX (
FILTER ( ALL ( Dimdate ), Dimdate[WeekOfYear] < MAX ( Dimdate[WeekOfYear] ) ),
[WeekIndex]
),
MAX ( Dimdate[WeekOfYear] )
)
RETURN
CALCULATE (
[SUM_Sales],
FILTER ( ALL ( Dimdate ), Dimdate[WeekOfYear] = LastWeek_notnullsales )
)
