Dax Table Summarize using Lookup

[NMOORE]

Hi,

I want to summarize a table keeping the corresponding values/Dates from a neighbouring column after an expression.

As the example shows I'm hoping to summarize the animals, calculate the earlisest (min) Analysis Date, and keep it's neighbouring FInalise Date.

Appreciate any help.

Thanks

IDEAL_Backtest_Details = 
ADDCOLUMNS( 
    SUMMARIZE(Backtest_Details, 
              Backtest_Details[Animals], 
              "Analysis Date",  min(Backtest_Details[Analysis Date])
    )

    , "Final Date", 
            LOOKUPVALUE(Backtest_Details[Final Date], 
                  Backtest_Details[Animals], [Animals],
                  Backtest_Details[Analysis Date],  [Analysis Date])
 )

something like this?

Hi @NMOORE 

if you're looking for a calculated table solution, you may try

NewTable =
GENERATE (
VALUES ( 'Table'[Animals] ),
CALCULATETABLE (
TOPN (
1,
SELECTCOLUMNS (
'Table',
"Analysis Date", 'Table'[Analysis Date],
"Finalise Date", 'Table'[Finalise Date]
),
'Table'[Analysis Date], ASC
)
)
)

No DAX needs to be harmed for this,  You can do this entirely in Power Query.  Sort by Analysis Date ascending and then deduplicate by Animals.

Yes, easy in Power Query, already accomplished. The question was for DAX

Hi, Thanks so much for your reply, I was trying to understand summarize and add columns better as I was half-way there but will look at understanding what you did here next week. Thanks again
