Images 1&2 are with reference to the YouTube video titled "AGRIBALYSE in openLCA & Pizza LCA case study". Transport to Distribution and Supermarket has "Reference Process Name" as shown in image (2). When I am performing the LCA using the "Reference Process Name", the unit for the same is showing in KG as shown in the image (3). How to get the units in KG*KM? Image (2) is titled "Packaging and Transport processes are with the flow referring to the existing processes in the database". What does that mean?
