disable multiple dialog user logins to RF SCANNER

We have requirement where we need to disable multiple dialog user logins to RF SCANNER and allow Service users to be able to login multiple times.

We tested this login/disable_multi_gui_loginparameter and it’s working when logging in from GUI but it’s allowing multi login if we login to RF Scanner (ITS SERVICE).

please can you advice whether it is possible.

thanks,
Ranjith
