I have a bit of a newbie modeling question. I have a process that`s linked to several other processes using flows. That process the becomes the reference for a product. When I open the product and look at the model graph, all of the linked processes are show except for one. When I go back to the reference process, and check the allocation tab, I see that one of my linked process contributes a quantity of zero. I`m not sure that one is related to the other, but that`s what I see. Can anyone tell me what might cause this situation. One thing I looked at was whether the locations all made sense. I made sure that everything was set to RNA (North America) to make sure that was all consistent.
