Hi,
i'm using global variable for several process but i have a probleme with one of them. My sub process is calling a process, in my process i affect value to the global variable, when i return in my sub process the value of global variable is lost....

Hi, you should first check on the subprocess plugin if "Backup job information" is checked. It should not for what you want to do.
Also double check if this variable is not updated within a script or in another plugin.

Sorry but I have already checked all this. I created a specific global variable and the result is the same. For information, here is the general process: General process is calling a sub-process, in my sub-process i called another process (passing meadata), this process return data to the sub-process who have calling using global variable...
I don't know if this is very clear

Hi, what you described is what I tested. If you still get issues with it, I would suggest you to contact your local support team.
