Hi, a system process is result of an aggregation of several unit processes. Unit processes are smallest modeling units, as defined in ISO 14040.

Hi Giuliana & Francesca,
well if you open a unit process and a system process for the same product, you should see differences - typically, since the system process aggregates the whole life cycle, it contains many more elementary flows.
Best wishes,
