I built models in ecoinvent 10 APOS system process database, and now I need to move these models to ecoinvent 10 APOS unit process database. But when I imported the models to the intended database, almost the flows lost the providers. And there are many flows and processes in my models. I don't wanna select the providers manually again. Do anyone know the problems of the missing providers or has some suggestions for dealing with those missing providers?
