Many flows in the EF database lack providers.

Question

Hello, during the modeling process, I found that some flows in the EF database do not have corresponding providers (for example, electricity). If I cannot link them to the corresponding providers, I will not be able to calculate their environmental impacts. So, are there any good solutions now? Looking forward to your reply.

Answer 1

You need to complete the supply chain manually, in the model graph e.g., or, these are already fully aggregated system processes.
