If you have more than one application server, use
AL08 instead of SM04.
or
It is because they are at the logon screen which has established a
connection.
You will notice that the transaction code shown when there is no user name is
SESSION_MANAGER.
This shows you which workstations out there have the login screen up but have
not yet entered a user name and password.
The transaction column shows the Last executed transaction code.
Sometimes your users will have multiple sessions open. If they do, to the
system, it is the same as multiple logins as it relates to the resources used
etc.
So the user name will show up more than once in AL08.
Under the application server they are logged into, each instance of that user
name on that application server represents a session open.
For instance if you run AL08, you will
have your name show up at least twice on the application server you are logged
into.
One will show AL08 and the other will not
have a transaction next to it.
Then you will notice your user name showing up on all other application
servers with no transaction. This is because you are using
AL08.
