How to Disable Multiple Login in SAP GUI

How to Disable Multiple Login in SAP GUI login/disable_multi_gui_login

By default, SAP users can have a multiple logons to SAP system but we can disable the function. If the function is disable, multiple dialog logons to (in the same client and under the same user name) are blocked by the system: When the system recognizes a multiple logon, it displays a dialog box with the options “Terminate the current sessions” or “Terminate this logon”. This parameter works with SAPGUI logons.

1. Go to RZ10. Select the Instance profile, choose Extended maintenance and create a new parameterlogin/disable_multi_gui_login (if it’s not created yet)
