Hi everyone,

I have some questions regarding dummy processes in LCA modelling. I'm currently using GaBi version 10. The questions are as follows:

1) In what cases does the error message "connection not possible" occur when modelling with dummy processes? That is the error message i receive when connecting my dummy process to another process.

2) I had created a production process in GaBi, which delivers four products. Afterwards, i created a dummy process for each of the four products, so that i can then set my most important product according to which i want to scale the rest of the processes as fixed.

Am i supposed to enter input and output data into the dummy process (since i want to set the process as fixed and want to scale everything else according to it) or do i leave the input and output data open?

Essentially, the question is: what data do i need to enter/ feed into the dummy process?

3) Can i integrate a dummy process into a plan without adding any information on input and output data into that dummy process? For example, if i'm creating a gate to gate modell of my product and need to add a certain input for which i do not have any data into the plan.

All help is appreciated.

Kind regards

Inka
