To call a function module in R/3, you must set up a connection to an R/3 application server. Only one
connection is possible for each server object. There are two ways of setting up a connection:
“Logon” method:
You should use this method if the user has to enter most of the connection information. Since it
automatically displays a dialog field for entry of the logon information, you then do not need to code
this.
“Open” method:
You should use this method if you can set all the connection information in the program, since no
dialog field is automatically displayed in this case. The “Open” method works only if all the logon
information is predefined.
