Subtract a top row value to another row from Matrix

[jasonjklim]

I am trying to establish a matrix table in PBI. 

One of the calculation is subtracting a top row value to another row from a matrix.

For example, 

I used DAX to do the samething. 

Drivers value2 = 
VAR production =
calculate(sum('Summary Data'[Value])/1000000,
    'Expense Roll up Mapping'[Expense Layer 3] ="Production Labor")
var adl2 =
    calculate(sum('Summary Data'[Value])/1000000,
    'Expense Roll up Mapping'[Expense Layer 3] ="Associate Domestic Labor",
    ALL('Summary Data'[New BU])
    )
var adl =
    calculate(sum('Summary Data'[Value])/1000000,
    'Summary Data'[Expense RollUp_P&L] ="Associate Domestic Labor"
    )
return
    SWITCH(SELECTEDVALUE('Expense Roll up Mapping'[Expense Layer 3]),
    "Production Labor", IF(ISBLANK(production),0, production), 
    "Associate Domestic Labor",  IF(ISBLANK(adl2-production), 0 ,adl2-production))

However, the result is the following:

I guess that in matrix, my Associate Domestic Labor row in expense layer 3 can't subtract different rows' values, production from the same table.

Is there any way that I can get this?

Please advise.

Thank you.
