Identify Duplicates and Redirect records

I have columns 1 to 7 . Column 1 , 2 and 3 has to be unique.

So i am using aggregate  , select column 1, 2 and 3 with group by and count(*).

Using conditional split helps me to identify duplicates and redirect records. 

But the issue is , I want other non-key columns also passthrough the next steps .

can you please say how can I achieve that.
