Want to disable multiple logon restriction only for some users

Hi all,

Good day....

I want to restrict multiple logon restriction for some users in my system.

As of my knowledge in SAP there is one parameter, login/disable_multi_gui_login=1.If we use the above parameter , then all users should be restricted to use multi login, right?

But i want to allow some users to do the multiple logon. I found one parameter ,login/multi_login_users=username1,username2,username3.

I used the above parameter. But in RZ10, i created this profile and added our users in "TWO LINES" .

But in SAP, it is clearly stating that "Each username is separated by comma and do not leave space between the username." but here the problem is i cannot able to add whole users in a single line.

Is there any solution for this? I searched in SAP but i couldn't find any solution for this.

Please help
