Issue with Incorrect Environmental Impact Values in Product System

Question

I am facing an issue in openLCA where the environmental impact values (e.g., CO2 equivalent) are incorrect in my product system, especially regarding the transport processes. The individual processes give correct results, but when combined in the product system, the transport impacts either exceed 100% or show negative values.

Can you please help me fix this issue and ensure the transport impacts are correctly calculated in the product system?

Thank you.

Hi, this seems to be an issue with how you connected the processes in your model, which you see in your product system. Either post screenshots here (update your post) or try to describe what you did. Thank you!
