trying to convert dax column to measure

[vally57]

I was trying to convert this dax column in to measure which I'm failing, Can anyone of you help me on this?
IF('Table A'[Customer PO]=BLANK(),BLANK(),
CALCULATE(SUM('Table A'[Total Order]),
FILTER('Table A',
'Table A'[Customer PO]=EARLIER('Table A'[Customer PO])),
FILTER(
'Table A',
'Table A'[Order Status]<>"0- Cancelled"),
FILTER('Table A','Table A'[Category]<>"TAPA"),
FILTER('Table A','Table A'[Order Status]<>"1 - Spoils"),
FILTER('Table A','Table A'[Order Status]<>"2 - Return")))

TIA

@vally57 Maybe something like this:

Measure = 
  VAR __PO = MAX('Table A'[Customer PO])
  VAR __Result = 
    IF(__PO = BLANK(),
      BLANK(),
      CALCULATE(
        SUM('Table A'[Total Order]),
        ALL('Table A'),
        FILTER('Table A', 'Table A'[Customer PO]=__PO),
        FILTER('Table A', 'Table A'[Order Status]<>"0- Cancelled"),
        FILTER('Table A','Table A'[Category]<>"TAPA"),
        FILTER('Table A','Table A'[Order Status]<>"1 - Spoils"),
        FILTER('Table A','Table A'[Order Status]<>"2 - Return")
      )
    )
RETURN
  __Result

or

Measure = 
  VAR __PO = MAX('Table A'[Customer PO])
  VAR __Table = FILTER(ALL('Table A'), [Customer PO] = __PO && [Order Status] <> "0- Cancelled" && [Category <> "TAPA" && [Order Status] <> "1 - Spoils" && [Order Status] <> "2 - Return")
  VAR __Result = SUMX(__Table, [Total Order])
RETURN
  __Result
