Filter in multiple columns

Hi omelei86 
Please refer to sample file with the solution https://www.dropbox.com/t/YXMM3TcOQdZ9yboj

First create the filter table 

Filter Table = 
SELECTCOLUMNS ( 
    DISTINCT ( 
        UNION ( 
            VALUES ( Opportunities[Sales Team (Opp owner)] ), 
            VALUES ( Opportunities[Sales Team (Revenue responsible)] ) 
        )
    ),
    "Sales Team", [Sales Team (Opp owner)]
)

Then Create new measure

Filter = 
COUNTROWS ( 
    FILTER ( 
        Opportunities, 
        Opportunities[Sales Team (Opp owner)] IN ALLSELECTED ( 'Filter Table'[Sales Team] ) 
            || Opportunities[Sales Team (Revenue responsible)] IN ALLSELECTED  ( 'Filter Table'[Sales Team] ) 
    ) 
)

Place it in the filter pane of the table visual then select "Is not blank" and apply.
