Short text
Recognizing and Preventing Multiple Dialog User Logons
Description
As of Release 4.6, the R/3 System recognizes multiple dialog user logons under a single user account. If a user logs on more than once to the R/3 System, he or she is informed that a user session already exists. As its default configuration, the system informs the user that he or she is already logged on to the system, but allows him or her to proceed.
Note the following:
- This function applies to dialog logons from SAPgui only. It does not apply to system logons that occur using the Remote Function Call (RFC) or to logons over the Internet Transaction Server (ITS).
- It applies to individual R/3 user logon IDs (identified by user name and client in the R/3 System). For example, a user with accounts in different R/3 clients can still log on to each R/3 client, even if you have activated the option to prevent multiple logons.
- The function is independent of the frontend computer. The system recognizes multiple dialog logon attempts from a single user, regardless of whether the attempts come from a single front end or from different computers.
If desired, you can also configure the system to prevent multiple dialog logons.

Changes to the Interface
If a user attempts to log on more than once to an R/3 System from SAPgui:
- The system informs the user with a dialog box that he or she is already logged on.
- The user then has the following choices:
- He or she can continue with the current logon and end all other user sessions.
- If multiple logons are allowed, he or she can continue with the current logon and keep the other user sessions. (If multiple logons are not allowed, this option is not offered.)
- He or she can cancel the current logon attempt.
The user is informed of the consequences of his or her decision:
- If the user ends existing user sessions, data that has not been saved is lost.
- If the user continues with his or her current logon attempt without ending existing user sessions, then the system records his or her decision. The SAP AG reserves the right to analyze these records.
The default option is to cancel the current logon attempt.
