'System process' vs. 'Unit process' under Provider

Question

Hi all,

I do not fully understand the system (S) or unit (U) options under the Provider tab in Processes. If anyone has advice or a simple explanation I would be extremely grateful.

Thank you!

Answer 1

A system process is fully aggregated, a unit process is not, but can deliver the same product if the system process is the aggregated version of a specific unit process. I hope it`s clear now?
Thank you!

In the input of the system process they use mined ores. So if i want to be on the safe side, i should ask the drafter of the database which steps they included in the process?
