Report Last Non Blank Row

[FayeB1901]

Hi there
I'm trying to create a calculated column that returns the last non blank value by a given date. I've tried several DAX options but can't quite get this working. See data below - in this example I would expect a value of -75.71 for 10/11/21.

Thanks in advance
Faye

Hi @FayeB1901 

Try this:

Measure=
Var _A = max(table[Date])
If(isblank(max(table[value])),
calculate(max(table[value]),filter(all(table),table[Date]<_A&&table[value]<>blank())),
max(table[value])
)

Hi Vahid 

No unfortunately no good - not sure what is going on here with the calculation!

Try this:

Meas1ure =
VAR _A =
    MAX ( table[Date] )
VAR _B =
    CALCULATE (
        MAX ( table[Date] ),
        FILTER ( ALL ( table ), table[Date] < _A && table[value] <> BLANK () )
    )
RETURN
    IF (
        ISBLANK ( MAX ( table[value] ) ),
        CALCULATE ( MAX ( table[value] ), FILTER ( ALL ( table ), table[Date] = _B ) ),
        MAX ( table[value] )
    )

@Vahid got it - it was filter context - wanted ALLSELECTED not ALL. Thank you!

@VahidDM any ideas on how to calculate as a column? Those values are Lat/Lon that I need to plot on the map & ARCGIS won't work with a measure ...

@FayeB1901 

Try this to add a column:

Column=
VAR _A =
   [Date]
VAR _B =
    CALCULATE (
        MAX ( table[Date] ),
        FILTER ( ALL ( table ), table[Date] < _A && table[value] <> BLANK () )
    )
RETURN
    IF (
        ISBLANK ( [value] ),
        CALCULATE ( MAX ( table[value] ), FILTER ( ALL ( table ), table[Date] = _B ) ),
        [value] )
    )

@VahidDM no not quite - seems like a filter context thing, like it's using a result not from the relevant ID maybe?
