In my database I have duplicate elementary flows for some chemicals. I think this is a result of importing openLCA LCIA methods and ecoinvent 3.7.1 into the same database. One of the pair will have characterization factors listed in the 'impact factor' tab when viewing the flow. I want to use IPC to retrieve all of the flows that are missing impact factor and map them onto the flows that do have impact factors. However, in IPC, I do not see how to find the impact factors when the flow is retrieved with flow1=client.get(olca.Flow, UUID). that is flow1 does not have a property of impact factor. Thanks.
