By default, automatic logoff is not activated in the R/3 System. Users remain logged on no matter how long they may be inactive. You activate automatic logoff by setting the system profile parameter rdisp/gui_auto_logout to the number of seconds of inactivity you want to permit. Enter as a value for this parameter the number of seconds of inactivity that must elapse before a user is automatically logged off.

Once you have activated this function, inactive users are logged off once the idle-time limit has been exceeded. The system does not save data before logging off the user. Unsaved data will be lost. The system also does not display a logoff confirmation prompt.

A user is considered to be inactive after choosing ENTER, or after other actions that transfer control to the application server to which a user is logged on.

Procedure
To activate automatic logoff, proceed as follows:

Start the system profile maintenance function by choosing Tools -> CCMS -> Configuration -> Profile maintenance.
Define or maintain parameter rdisp/gui_auto_logout. Enter as a value for this parameter the number of seconds of inactivity that must elapse before a user is automatically logged off.

To activate automatic logoff throughout the system, set the parameter in the default profile (DEFAULT.PFL) . However, if you want to activate automatic logoff only for a specific SAP application, set the parameter in the profile for that particular instance.

Remember that many users are not "active" for extended periods of time. Such users may include:

Programmers or other users of SAP editors, who regularly work for long periods of time only using the frontend software.
Users who only occasionally enter data but who should not be logged off. Example: Production employees who only enter data in the R/3 System when, for example, materials are delivered.

You should either set a high value for parameter rdisp/gui_auto_logout, or deactivate automatic logoff on the servers on which such users are active. This protects these users from loss of data or the inconvenience of having to log on again.

You can activate automatic logoff selectively by server by setting the parameter only in the profiles for the relevant instance. You can also define logon groups and thereby specify which users should not be automatically logged off.

To deactivate automatic logoff, delete the parameter from your profile(s) or set it to the value 0.
