DAX Row minus Previous Row

[Archer]

Hi @BrianJ,
same error as previous !
I’ve put this in Calculated Column

PrevYieldValue = 

VAR SelRow = Orders[actual_finish_date]

VAR PrevDate =
CALCULATE(
    MAX( Orders[actual_finish_date]) ,
    FILTER(
        Orders,
        Orders[actual_finish_date] < SelRow
    ),
   ALL( Orders[actual_finish_date] )
)

VAR  Result =
CALCULATE(
    MAXX('Orders',SUM([del_quantity])/SUM([tot_quantity])*100 ),
    FILTER(
        Orders,
        Orders[actual_finish_date] = PrevDate
    )
)

RETURN
Result

I get an error as below

I have tried Measure and I get blank(No values)

PrevValue = 

VAR PrevDate =
CALCULATE(
    MAX( Orders[actual_finish_date]) ,
    FILTER(
        Orders,
        Orders[actual_finish_date] < Orders[actual_finish_date]

    ),
   ALL( Orders[actual_finish_date] )
)

VAR  Result =
CALCULATE(
    MAXX('Orders',SUM([delivered_quantity])/SUM([total_quantity])*100 ),
    FILTER(
        Orders,
        Orders[actual_finish_date] = PrevDate
    )
)

RETURN
Result

Thanks
