I red on the manual of Ecoinvent 3.4 for openLCA that the ecoinvent v.3.3 and 3.4 identifiers could not be updated to match with those in ecoinvent v.3.2; so a procedure for the conversion is suggested. The first step is "Download the zip file “Convert own datasets from ecoinvent v.3.2 to ecoinvent v.3.3” available in Nexus (i.e. ecoinvent v.2.2&v.3.3 > Database details > Additional documentation)". As you see from the following picture,,. the section Additional documentation is not available.

Could you help me to download the conversion file, please?

We have now added the script back to openLCA Nexus. py script location openLCA Nexus

And I also added an older documentation for 3.3 which explains these changes that are addressed (related to IDs) by the script. Let us please now if you find it useful!

Thank you very much, but I still have some problems:
1) That link only allows downloading the .py file ecoinvent_v_3_2_conversion_to_v_3_3_report_csv.py; as described in the guide, I would need two more files: “mapping_ei32_to_ei33.csv” and “categories_ei33.csv” whose directory must be set in the pyton editor.ù
2) This procedure is to convert a process from Ecoinvent 3.2 to Ecoinvent 3.3. The guide says that it also works for Ecoinvent 3.4. Bu should I change any setting for that ?
Thank you very much
Best regards
