Pattern in table

Hi MintuBaruah ,

Something like so?

Column = 
VAR PreviousDate_ =
    CALCULATE (
        MAX ( 'Table'[Date] ),
        FILTER (
            'Table',
            'Table'[Narrative] = EARLIER ( 'Table'[Narrative] )
                && 'Table'[Ref.] = EARLIER ( 'Table'[Ref.] )
                && 'Table'[Date] < EARLIER ( 'Table'[Date] )
        )
    )
VAR PreviousDebit_ =
    CALCULATE (
        MAX ( 'Table'[Debit] ),
        FILTER (
            'Table',
            'Table'[Narrative] = EARLIER ( 'Table'[Narrative] )
                && 'Table'[Ref.] = EARLIER ( 'Table'[Ref.] )
                && 'Table'[Date] = PreviousDate_
        )
    )
RETURN
    IF (
        'Table'[Debit] <> BLANK ()
            && PreviousDebit_ <> BLANK (),
        IF ( 'Table'[Debit] <> PreviousDebit_, "True" )
    )

Best Regards,
