Data Separator Value

Where I can assign Data Separator Value to Session Parameter designated to storing such value? I tried in Application Module and Session Module, but it didn't work - Session Parameter which stores Data Separator Value didn't change. For data separators I have a separate catalogue.

Looks like it's just a limitation of training version of the platform. In Prof version works fine.

Yes, it is! The training version of the platform has certain limitations, and this must be remembered
