Find Distinct Data - Based On Two Columns

Hi rhcentennialh ,

We use the following measure and get the expected result:

Not identified by Outside = 
IF (
    SELECTEDVALUE ( 'Table'[Code] )
        IN SELECTCOLUMNS ( FILTER ( ALLSELECTED ( 'Table' ), [Internal vs Outside] = "Internal" ), "c", [Code] ),
    BLANK (),
    "YES"
)

BTW, pbix as attached.

Hi rhcentennialh ,

Can it filter the data you want if we put the following measure into the Visual Filter then set the condition as greater than zero?  Please try it without the measure in the value filed of table visual.

Not identified by Outside 2 = 
IF (
    SELECTEDVALUE ( 'Table'[Code] )
        IN SELECTCOLUMNS ( FILTER ( ALLSELECTED ( 'Table' ), [Internal vs Outside] = "Internal" ), "c", [Code] ),
    0 ,
    1
)
