Hi Basthian,
Thanks again for your reply.
I have been reading your answers in this other thread OrderCreation and OrderConfirmation.
Now it is more clear for me, although I don't know how define exactly the second step. Do you know any documentation or link that I could use? I have checked specific official training about Integration Framework, but I haven't seen any content related to 'how create a sucessor step' for handling this requirement.
Kind Regards,
Toni
