Dax Table Summarize using Lookup

NMOORE — Thu, 04 Apr 2024 21:27:01 GMT

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?

IP: Backtest_Details

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
