Does not start with - DAX expression

[Anonymous]

Hi!  I'm looking for help on how to write a 'does not start with' DAX expression.

This is what I have right now, but doesn't seem to work:

Total Sales & Credit Memos = 
CALCULATE( 
        [Total Amount],
        (LEFT('CONSOL GLENTRY'[Document No_], 2) <> "GJ"
)

I'm looking to calculate all documents that 'do not' start with "GJ".

Any help would be appreciated!

@Anonymous wrap in MAX

Total Sales & Credit Memos = 
CALCULATE( 
        [Total Amount],
        (LEFT(MAX('CONSOL GLENTRY'[Document No_]), 2) <> "GJ"
)

hi @Anonymous 

try like:

Total Sales & Credit Memos = 

CALCULATE( 

        [Total Amount],

        FILTER(

            ALL('CONSOL GLENTRY'[Document No_]),

            LEFT('CONSOL GLENTRY'[Document No_], 2) <> "GJ"

         )

)
