DAX lastNonblankvalue not working as a measure

Question

Hi,

I am having issue with the last blank value as I am trying to show a tab with the Date - Value - last non empty value . I use the demo sample from dax.io ( the link include my code )
https://dax.do/dD83JH5nka6NhB/

The query I use is

define  
 measure Sales[Sales Amount Last]=  
LASTNONBLANKVALUE ( 'Date'[Date], [Sales Amount] )  
EVALUATE  
CALCULATETABLE (   
    ADDCOLUMNS ( VALUES ( 'Date'[Date] ), "Sales Amount", [Sales Amount] ,  
    "Last non blank",Sales[Sales Amount Last]   
    ),  
    'Date'[Date] >= DATE ( 2007, 2, 7 ) &&  
    'Date'[Date] <= DATE ( 2007, 2, 16 )   
)  

But I have the same blank on the column Sales Amount and the column Last non blank. I was expecting the Last non blank value to show the value from the previous day when blank.
But the result is similar in both column :

So I was expecting to see 15,502.99 on the column "Last non blank" for the date 2007-02-07. Any idea what I am missing ?

I am confused I think the ask should be

So I was expecting to see 15,502.99 on the column "Last non blank" for the date 2007-02-08. Any idea what I am missing ?

If thats the case , please use the below query .

-- FIRSTNONBLANKVALUE and LASTNONBLANKVALUE return the first and last
-- non blank values in the selection.
DEFINE
MEASURE Sales[Sales Amount Prev] =
CALCULATE ( [Sales Amount], PREVIOUSDAY ( 'Date'[Date] ) )
MEASURE Sales[Sales Amount Prev non] =
VAR LastAmount =
CALCULATE (
MAX ( 'Date'[Date] ),
FILTER ( ALL ( 'Date'[Date] ), 'Date'[Date] < MAX ( 'Date'[Date] ) )
)
VAR result =
CALCULATE ( [Sales Amount], 'Date'[Date] = LastAmount )
RETURN
if ([Sales Amount]=BLANK (),result,[Sales Amount])
EVALUATE
CALCULATETABLE (
ADDCOLUMNS (
VALUES ( 'Date'[Date] ),
"Sales Amount", [Sales Amount],
"last non blank ", Sales[Sales Amount Prev non]
),
'Date'[Date] >= DATE ( 2007, 2, 7 )
&& 'Date'[Date] <= DATE ( 2008, 2, 16 )
)
ORDER BY 'Date'[Date]

Please do let me know how it goes .
Thanks
Himanshu
