Get most recent non-null value?

[soliverc]

I have a table like this. Notice the blank values towards the bottom.

I would like to get the value of the latest date, but the value can't be null.

My DAX formula is bringing back the value of the latest date (19/12/2021) which is null, however I want to bring back the latest non-null value, which is for the date 21/11/2021.

Here is what I have tried so far:

Latest Value = 
CALCULATE(
    // get sum of value column
    SUM('Table1'[Value]), 
    // where value is not blank, and date is max date
    'Table1'[Value] <> BLANK() && Table1[Date] = MAX(Table1[Date])
)

I get the value: null / blank

I thought this should bring back the figure 305? Because my conditions are:

where value is not null AND where date = max date

Shouldn't the max date now be 21/11/21 because the nulls have been removed?

Another piece of DAX I've tried, using the filter function.

Latest Value = CALCULATE(
    SUM('Table1'[Value]),
    FILTER(ALL('Table1'),
    'Table1'[Value] <> BLANK()
    &&
    'Table1'[Date] = MAX('Table1'[Date]))

I get the same result: null

Where am I going wrong? I think it's something to do with my max date section.

Unfortunately all file hosters are blocked in work, so I can't share this dummy file. However I hope I have simplified the data enough to just quickly get the idea. 

If there is an attachment button, please let me know because I can't find it. 

Many thanks

Hi @soliverc ,

1.If one date has one value, you could simply use LASTNOTBLANK():

Measure = LASTNONBLANK('Table'[Value],MAX('Table'[Date]))

2. If you want to get the sum of the last date, please try to get the last and value<> blank date firstly and then sum:

Measure 2 = CALCULATE(SUM('Table'[Value]),FILTER('Table',[Date]=MAXX(FILTER('Table',[Value]<>BLANK()),[Date])))

Output:

@soliverc ,

Max non blank date

Maxx(filter(Table, not(isblank(Table[Value])) , Table[Date]))

or

Maxx(filter(allselected(Table), not(isblank(Table[Value])) , Table[Date]))
