there is something about the economic/physical allocation that I don't understand and would appreciate any insights or tips. I'm using 1.9.0 (with Agribalyse,ILCD and AgriFoot) and I’m creating processes and flows from scratch. I have a multioutput process  with a main product and 2 co-products. I want to see how LCIA results change applying physical or economic allocation but I got the same results! I have added an economic flow property to each product flow (using "market price") and they all have the same *reference property* (Mass). I have created the Project and in Compared product systems I drag and drop 2 times my Product system, so 2 options with the different Allocation method set. Why I got the same results? Is there something I'm doing wrong?

You do not do something wrong, if you do not have prices for the product then the phyiscal amount is used for the economic allocation.

EDIT I got it! I have to add the prices in the column Costs/revenues for the outputs in the Process. Now it works. is it right?
