There are some limitations to the changes you can make to your SimaPro model, while still using the same item descriptors in your report.
What cannot be changed?
The items and options you define in your calculation setup cannot be edited. If you want to make changes to your calculation setup (for example, by choosing another impact assessment method), the item descriptor will not be updated. Instead, you have to create a new item descriptor and paste that into your report.
What can be changed?
- The underlying product stages, processes, amounts, etc.
If you make changes to these aspects, they will be incorporated and updated automatically in your report.
