Please if you could help me to know the reason that error message is shown

Best regards.

Answer 1

Hello Oscar,
this import via csv is often difficult since SimaPro does not have unique id numbers, so that it needs some refactoring before a complete and consistent model is created. From what you sent it is hard to see where the issue is, but something essential is missing (thus the Nullpointer exception). If you want you can contact us directly, we have some experiences meanwhile in reading and converting SimaPro models.
Best wishes,
Andreas
