DAX cumulative total including null values at the end

[sabd80]

Hi All,
I have the measure Sales Cumulative, it calculate the sum corecctly until it reaches blank value, then it shows the first value for null values, which from week 104, I would like to see the previous value if the value is blank.
From week 104 to 121, I would like to see the value 4,723,049
This is the dax:

Sales Cumulative =

CALCULATE(

   SUM( 'Consolidated Data'[Dollar Sales]),

   FILTER(ALLSELECTED('Consolidated Data'),

    'Consolidated Data'[Week Reference Age]<=MAX('Consolidated Data'[Week Reference Age])

   )

)

and this the data:

For that you are going to need a weeks table that is linked to your data table.

You can make on as a calculated table with this DAX

Weeks = DISTINCT ( 'Consolidated Data'[Week Reference Age] )

Then link it to your data table in the model

Put the Week Reference Age from the new table in your visual and modify your measure like this:

Sales Cumulative = 
VAR _MaxDate =  MAX ( Weeks[Week Reference Age] )
RETURN
CALCULATE (
    SUM ( 'Consolidated Data'[Dollar Sales] ), Weeks[Week Reference Age] <= _MaxDate
)

You can see the new Sales Cumulative measure correctly calcs the running total, even when a single product is selected.

Thanks for the quick reply.
I have tried the provided dax too. One thing I forgot to mention is I have slicer for the Prodcut, when I select I a particular product, it shows only the weeks tht have sales value, I would like to see the values for the consecutive weeks.
For exampl when select a product that has sales only in week 84, it shows only that week:

But what I would like to see the sales figure 4 from week 84 to week 121 for the that particular product:

@sabd80 

Is it possible that the value in your column 'Consolidated Data'[Week Reference Age] is different that the column you are showing in Week in your table?  Your measure works for me:

You also don't need the FILTER statement, you can just do it like this.

Sales Cumulative =
CALCULATE (
    SUM ( 'Consolidated Data'[Dollar Sales] ),
    'Consolidated Data'[Week Reference Age] <= MAX ( 'Consolidated Data'[Week Reference Age] )
)
