Hi,

I am wondering how the impact analysis result is calculated.

 I typed flows manually and found no impact factor value in the impact factors sheet. Though I clicked open in that sheet it didn't work. I made a process with those flows(inputs and outputs) and there is no impact analysis result.  

What should I do to get impact analysis results? Do I need to type impact factors manually for individual flows?

Or is it only available for databases in Nexus not for data typed manually?

I've struggled with this issue for a long time but couldn't get it. Hope I can get the answer here. Thanks.

Regards, 

Stella

Yes, when you create new flows, also if they have the same name as existing flows, you need to create new characterization factors in the respective impact categories for them.
