Dear OpenLCA,
i'm currently facing an allocation problem. I've a carreer process with total production and as created products with different sizes as bellow
Then, in allocation, i've calculated physical allocations for each created products
To here no problem, but i've been calculated a product where there are 2 created products from thi career with the same weight proportion in formula. One allocation is 0.16, the otherone is 0.09 allocation factor.
However, whatever the used method of calculation (recipe, 15804 ...) the result is the same with forced physical allocation. Same weight ratio gives the same CO2 results wheras allocation factors are different (les vallons v2 in following picture).
i've tried software update with no change.
When i'm calculating without allocation, in fact, there are allocation with the same weight ratio
So what's wrong. There a kind of inversion : none allocation selected gives an allocation (which by the way gives a very high value) wheras physical allocation gives no allocation.
I've been searching the problem without any solutions.
What i remember, is that in the old 1.x version the allocation used to work.
For information I'm using 3.9.1 ecoinvent database.
Thanks in advance
