The product flow "diesel | market for diesel" with location "Europe without Switzerland" (this is the one I'm interested in), coming from Ecoinvent 3.4, is not produced by any process.

I thought this product flow would be the quantitative reference of "market for diesel | diesel | Cutoff, S" whith location "Europe without Switzerland". But it's the product flow "diesel" (with no location) that is the quantitative reference.

I don't understand, it looks to me that I have to select "diesel" and specify the provider I'm interested in.

Can anyone help me ? I guess it's a basic question but I really don't understand at the moment.

The product flow is only "diesel", which makes sense I think; the diesel is the same, whether it comes from a market process or from somewhere else. I don't fully understand though probably what you need - if you want to use a diesel from a certain provider process then indeed you need to select this process (with its location) as provider.

Ok, that makes sense.

Sorry, I am creating a product system programatically (in Java), from openLCA Ecospold1 IExchange objects. I wanted to understand which name I should give to my IExchange so that it maps with the right flow in openLCA. So here for example, I understood that my exchange should have the "diesel"name, and no location. Then, once the mapping is done, I should specify the provider. Tell me if I got something wrong.
