A session is basically another SAP instance on your screen. Multiple sessions allow you to work on more than one task at a time. This saves you time and reduces the need to jump from screen to screen.
A record can only be edited by one user in one session at a time. Multiple write access to the same record is denied.
To display a list of all sessions for a system, enter /o in the transaction field. A dialog box appears.
The system administrator specifies the maximum number of open sessions you can have at any time (between two and six). To create a new session is the same as logging on to the system again. Each session is independent. Whatever you do on one session (for example, closing it) does not affect the other sessions.
Too many open sessions can result in slower system performance. Therefore, your system administrator may limit the number of sessions you can create to fewer than six.
To create a new session from anywhere in the system, perform one of the following:
· Choose System ® Create session from the menu bar
· Choose with the quick info text Create a new session
The system opens an additional screen. The new session becomes the active session and remains so until you click or create another session.
Each session has a session number. It is part of the system information in the status bar and is located next to the transaction name.
After you have finished using a session, you should close it, because each session uses system resources that can affect the SAP system performance.
If you only have only one session open and you close it, you will log off from the system. However, before logging you off, the system prompts you to save your data.
Before you close a session, save any data you need. When you close a session, the system does NOT prompt you to save your data.
You can close a session in the following ways:
· Choose System ® End session
· Click Close in the right corner of the active session.
· Enter /i in the transaction field of the session you want to close
· To close a specific session, in the transaction field of any session, enter /i followed by the number of the session you want to close. For example,/i3 to close the third session.
You can close all the sessions at once in two ways:
· Enter /nend in the transaction field.
· Enter /nex in the transaction field.
The difference between the two commands is that /nend prompts you before closing all sessions, whereas /nex closes all the sessions without prompting.
