pin contribution of the result monte carlo simulation is 0??

Question

I want to see the contribution of the different processes in the Monte Carlo simulation, but when I check display in chart they all show 0. Why

Answer 1

maybe since these are unit processes?

Comments

have linked to the provider

ok but these are the direct contributions for the processes (otherwise you would have a lot of double-counting) so setting the provider does not affect these results. If you want to see supply chain contributions, turn entire supply chains into product systems and link them in one major product system. Then select these product systems here.

thanks, What I want to analyse is the uncertainty of the different data to the final LCA result
