I purchased the ecoinvent database from OpenLCA nexus and downloaded V3.4- Cut-off approach. There are three files for this approach:
However, when I try to upload these files, only the last one of these gets successfully uploaded. When I try to upload the other two, I always get the message: "Database Import Failed".
Could you please tell me what I could be doing wrong? and what those first two files contain, that is not a part of the third database that does get uploaded successfully.
Thanks in advance,
