Direct contribution is the process itself, upstream total all processes "before" this process.

Thanks for your help.

Can you also explain why the the direct contribution and upstream total is often the same, even the percentage? Moreover, I don't understand why the direct contribution of processes I created myself is 0.00. Is it, because it uses the processes before which are added in upstream total?

Thanks in avance.
