Distributing Value into specified category

Hi KrikkitWars42 ,

I have created a  simple sample, please refer to it to see if it helps you.

Create measures.

Measure =
VAR _2 =
    IF ( MAX ( 'Table'[Index] ) >= 4, [Budget by categorym], BLANK () )
RETURN
    SUMX (
        FILTER ( ( 'Table' ), 'Table'[Index] >= SELECTEDVALUE ( 'Table'[Index] ) ),
        _2
    )

Measure2 =
VAR _1 = - ( -150 )
VAR _2 =
    SUMX (
        FILTER ( ALL ( 'Table' ), 'Table'[Index] <= SELECTEDVALUE ( 'Table'[Index] ) ),
        [Measure]
    )
VAR _re =
    IF ( _1 <= _2, MAX ( 'Table'[purchase] ), BLANK () )
RETURN
    _re

result =
VAR _1 =
    MINX ( FILTER ( ALL ( 'Table' ), [Measure 2] <> BLANK () ), 'Table'[Index] )
RETURN
    IF (
        MAX ( 'Table'[Index] ) <= _1
            && [Measure] <> BLANK (),
        MAX ( 'Table'[purchase] ),
        BLANK ()
    )
