AL08 shows the list of all the users who are logged on to the system globally or for all the instances in the system which are active. It shows all the active instances and number of active users in the system. It contains the following columns.
1) Instance - It shows the Instance into which the user logged in
2) Client - It displays the SAP client into which the user is Logged in
3) User Names - SAP user name
4) Terminal - Terminal at which the user is working
5) T-code - Last executed transaction code
6) Time - Time at which the user last initiated a dialog step by entering data
7) External Sessions - Number of External sessions the user has opened
8) Internal Sessions - Number of Internal sessions the user has opened
The Difference between External and Internal sessions
Internal Session: It is the memory allocated for a program during execution. When we call a program using SUBMIT or Call Transaction then it will be loaded in a new internal Session. To exchange the data between internal sessions we can use ABAP MEMORY.
External Session: It is nothing but a window. Which we can create using SYSTEM -> CREATE SESSION.
We can open up to 6 external sessions (this is set by Basis of course).
We can use SAP Memory to exchange the data between External sessions in a Login.
