Basic explanation of Connection, Session and Children

[Former Member]

Hello,

I started doing scripts to connect to SAP automatically and I wish to better understand Connection, Session, and Children.

How are they related to each others, counted, etc?

example with the classic begenning before connection:

'Connection-------------------------------------------- 
 Set SapGuiAuto = GetObject("SAPGUI")   'Get the SAP GUI Scripting object 
Set SAPApp = SapGuiAuto.GetScriptingEngine     'Get the currently running SAP GUI 
Set SAPCon = SAPApp.OpenConnectionByConnectionString("/SAP_CODEPAGE=1100  /FULLMENU  /M/peadbe0.eu.corp/S/3690/G/SAP_LAN /UPDOWNLOAD_CP=2", True) 
Set Session = SAPCon.Children(0) 

So it seems:

• Upper level is the connection to a server. There can be multiple connection to same server by multiple users.

• These users create always one session at minimum but can open parallel SAP windows to run parallel transaction for example. Hence they create more session.

Am I right? And then, what about the children? What means the "Set Session = SAPCon.Children(0)"?

Thanks for the help

Hello.

SAPCon is the Connection to an server

This Connection can have multiple sessions (children).

"Set Session = SAPCon.Children(0)" => this is the first session to binded SAP Server

"Set Session = SAPCon.Children(1)" => this is the second (parallel) session to binded SAP Server
