Hello,

I am trying to create a product system using OpenLCA. The product system uses a same process more than one time. Nonetheless, when I try to drop the process twice, a pop-up window says that the process is already in the product system. For that reason, I have to duplicate the same process in the database.

I appreciate your guidelines.

Hi, this is quite common, but you do not need to add the same process several times but only reference the process. You can check e.g. in some ecoinvent product systems in openLCA where some electricity or transport processes are used 100s of times.

All the best,

Andreas
