Thank you so much for your reply. I downloaded the FEDEFL TRACI version, and still getting negative results. Do you think it might have to do something with the 'Autolink process' ? Because I was trying to figure out what it does by checking the Autolink process and figured out that removing 1 or 2 upstream processes supply chain, it gives me positive impact results?! Though I removed those supply chain randomly, not really understood it. I wanted to add Screen shots from my analysis here but couldn't add image in comment
