At process level, I modelled 2 processes with various inputs and outputs, lets call them A and B. And in both processes, I modified the output flows using the same flows. Product system of A gives the impact results, but the product system of B does not calculate the impact results. The LCIs of outputs of A and B are identical, and their inputs are similar (I exported the excels of processes A and B). I also checked the model graph which looks fine. I tried troubleshooting, such as deleting and re-creating the product systems, close/open database, close/open OpenLCA.. etc.. yet not working.. why would that me. If needed I can share the LCI excel.
Thank you,
