Dear community,


We successfully mapped all flows from a source system into an ecoinvent dataset. After clicking on "Check Mappings" all flows get marked green. After the option "Apply on database" and selecting the corresponding processes in which they are to be applied all flow-status become "target flow, the flow in the database has no corresponding unit". That is quite confusing as I have previously checked all flows. How can I solve the appearance of the error message and successful apply the flows on the database?

Thanks in advance!

In the corresponding csv file the UUID of the unit of the source flow was missing. After adding the UUID directly in the CSV file the mapping works.
