Hello
I'm trying to understand the real advantage to use libraries (Ecoinvent library).
When I import Ecoinvent library in the database everything begins to be complicated.
I can not modify input/output data of a dataset unless I copy it.
If I try to calculate directly a dataset I must create a product system.....?????
If I try to read the direct impact I obtain errors so it's unuseful.
Someone can explain me how to use correctly libraries?
The openLCA manual explain only how to import library in a database but it does not give information how to use it.
Thanks and sorry if my question is silly.
