having no producer for flow

Question

Hi,

  I do not have any provider for my inputs (flows) at the process.Does any body know why?

thanks

Answer 1

Check that there exists a process in your database that has the flow as an output.  Make sure it is the exact same flow, open the flow and in the viewer expand the "Used in processes".  If it does not list "Produced by" than there are no processes that have it as an output.

Maybe to add that openLCA can deal with the situation that you do not havea provider for a product in your database; in the calculation result, you will then see a product on the input side of the inventory.

Answer 2

Hi,

Maybe because of elementary flow. Check this out:
