Why is using version 3.4 of ecoinvent in Openlca no longer provided by most providers?

Question

Four years ago I used to work with Open LCA using ecoinvent 3.4 database, but now that I am retaking the software use and the same database most of the products no longer offer the list of providers as before. I have only changed the use of the Open LCA version to now use version 1.10.3 when before it worked fine with version 1.7

Answer 1

Hi, the quantitative reference was implemented differently in 1.7 than it is now, and the migration of databases does consider this only from one version to the next; if you want, you can try opening the database in 1.8, etc. Let me know.

All the best, thank you, Andreas

Hi, I tried with Open LCA 1.7 and it didn't work. I haven't tried with 1.8 yet but I guess that if doesn't work with 1.7, it won't work with 1.8

As I had tried to explain, the new database structure for the quantitative reference was introduced after 1.7, and we only address migration from one version of openLCA to the next, thus my idea to try 1.8 (instead of 1.10.3). But as you want of course.

Ok, I will try with 1.8 version. I have nothing to lose trying
