DAX LOOKUPVALUE with MAX

[Anonymous]

Hi,

Im trying to lookup a value from another table with MAX

I have two data tables like this:

Table1:

Table2:

What I'd like to do is, for the empty values in "Table2[Latest Result]" to find the value in "Table1[Result]" based on the highest number in "Table1[Unix]", so i get the latest update from each ID.

So that Table2 ends as:

I have tried:

Latest Result = LOOKUPVALUE ( 'Table1'[Result] ; 'Table2'[ID] ; MAX ( 'Table1'[Time] ) )

But gives me all blank, not sure how to fix this.

Anyone that got an idea?

Hi @Anonymous 

Try this for your calculated column in Table2:

LatestResult =
VAR Latest_Time_ =
    CALCULATE (
        MAX ( Table1[Time] ),
        FILTER ( ALL ( Table1[ID] ), Table1[ID] = Table2[ID] )
    )
RETURN
    LOOKUPVALUE (
        Table1[Result],
        Table1[ID], Table2[ID],
        Table1[Time], Latest_Time_
    )

@Anonymous ,

You can also create a calculate column in table2 using DAX below:

Latest Result = 
VAR Current_ID = Table2[ID]
VAR Max_Unix_Per_ID = CALCULATE(MAX(Table1[Unix]), FILTER(Table1, Table1[ID] = Current_ID))
RETURN
CALCULATE(MAX(Table1[Result]), FILTER(Table1, Table1[Unix] = Max_Unix_Per_ID))
