I am currently working on a project on openlca and any of the databases do not apply to my country (mauritius). However, since we import some products, i can use these on the software that are adapted to my country. However, i will have to add some data manually (like transport and electricity). My question is how do i add these manually? (i am under the impression that i have to work with the composition of the products and use the elementary flows available to create processes/products). Also, how do i add a provider?
