Removing ports in Lookup transformation that are not needed downstream?

Hi All,

 

I want to remove unused ports in Lookup transformation which are not needed downstream(to improve the performance).

Will writing a SQL ovverride statement which includes used input and output columns will be enough to achieve it?or do i need to include some other steps as well?

In my current scenario all columns are used in lookup even though some columns are not required.

 

Thanks.
