Hi,
I have a little issue,
In my development model i have created a process in order to import members of a hierarchy list regarding code, name and parent, in one step of the hierarchy for exemple let say that we have 4000 lines, in the lower level we have 40 000 each with parent, code and name, when i run this process with my import file in the development model it works perfectly but when i do it in the UAT model i have a message saying that i don't have enough place, can't get why it works in the development model and not in the UAT

Could someone give me advices ?
Thank you
