Need help with my process bpmn

is this process correct


While it may pass the syntactic rules of BPMN, it doesn’t actually follow good practices of BPMN.

You should not be sending messages and receiving them in the same process. (See Demander Bulletin d’adhesion and Reception demande BA )

If this were a set of tasks on a web-page, would Gestionnaire even make the request? Or would a task simply appear on Production DIM’s task list? Same thing with the documents au BO

Does Production DIM actually perform an action (in this process) other than send documents? Could they not simply be replaced by a system function that automatically replies to the request for documents? Same thing with Bureau d’ordre.
