Why is openlca multi-out process calculation not consistent with the same input-output elsewhere?

Question

Brethren, I have a problem with openlca MULTI_OUTPUT PROCESS. DO you know that I have two different PROCESSES I produced, And they are the same. Example

Process 1- pharmaceutical products 

Process 2 - pharmaceutical products(2)

THESE INPUTS AND OUTPUTS ARE THE SAME YET WIT DIFFERENT REQUIRED AMOUNTS AND RESULTS.

Process 1 has 17 output processes like stage 1, 2, 3, 4......17 having a FU of last product as 1mg.

Process 2 has 17 output processes like stage 1, 2, 3, 4......17 having a FU of last product as 1mg.

Yet, I  do get DIFFERENT ''RESULTS'' and DIFFERENT ''REQUIRED AMOUNTS''

SEE below the images

Please why are these calculations always not consistent in its calculations?

Why I concluded this openlca is not consistent, I replicated processes with the same input and outputs. These have been tested using different process 1, process 2 process 3 with 3 consecutively different results and required amount being different from each other.

Hello, I think I do not understand, you are a bit familiar with LCA methodology I assume? Can you explain what you mean by "process 1 has 17 output processes like stage" etc. - thank you. You have identical processes but the amounts in the processes are different? If you edit your question, you can directly upload images to the forum server, that is better than posting links. Thank you again, Andreas

Hi,

To understand my position better, I would like you to watch this tutorial video where multi-output process is used.
