Extract Maximum value

Hi OscarSuarez10,

You could create column like below by Mcode

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("VY3BCcAwDMR28bsF2+dznVlC91+jJQ0Ff4WE5hSTQ06vYEK15D6m+EJJL7eNsBDDjGOjP2SO4S2Ewzf6Q0Zt9IUwXuxH03yzdlQFrmrHTHj0Y2REWjuC0FrW/QA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [YEAR = _t, #"CUMULATIVE CASHFLOW" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"YEAR", Int64.Type}, {"CUMULATIVE CASHFLOW", Int64.Type}}),
    #"Added Custom" = Table.AddColumn( Table.AddIndexColumn(#"Changed Type", "Index", 1, 1), "Custom group", each Number.RoundUp([Index]/3)),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Index"})
in
    #"Removed Columns"

Then use measure like below

Measure =
VAR maxt =
    MAXX (
        SUMMARIZE (
            'Table (2)',
            'Table (2)'[Custom group],
            "sum", CALCULATE (
                MAX ( 'Table (2)'[CUMULATIVE CASHFLOW] ),
                ALLEXCEPT ( 'Table (2)', 'Table (2)'[Custom group] )
            )
        ),
        [sum]
    )
RETURN
    IF (
        MIN ( 'Table (2)'[CUMULATIVE CASHFLOW] ) = maxt,
        MIN ( 'Table (2)'[YEAR] ),
        ""
    )

Measure 2 =
VAR maxt =
    MAXX (
        SUMMARIZE (
            'Table (2)',
            'Table (2)'[Custom group],
            "sum", CALCULATE (
                MAX ( 'Table (2)'[CUMULATIVE CASHFLOW] ),
                ALLEXCEPT ( 'Table (2)', 'Table (2)'[Custom group] )
            )
        ),
        [sum]
    )
RETURN
    IF ( MIN ( 'Table (2)'[CUMULATIVE CASHFLOW] ) = maxt, maxt, "" )

You could refer to my sample
