I use GuiXT for
several different SAP systems. When I work in the SAP OSS
system, I do not want to use GuiXT, so I deactivate it in the
sapgui options, and activate it again after finishing my
work in OSS. Or is there a simpler way?
Yes, you can specify all systems
(in which you want GuiXT to be active) in
GuiXT profile: "Enabled systems".
