# sapgui_open_connection_ex

Connection and Session Functions

Opens a connection to the SAP server specified by a connection string.

    int sapgui_open_connection_ex( const char *connection_string, const char *connection_name, const char *connection_id, [args,] LAST );

connection_string | A unique string identifying the SAP server.
connection_name | A name for the connection, defined in the SAP client installation.
connection_id | The connection identifier
args | Optional Arguments
LAST | A marker indicating the end of the argument list. Not required if Optional Arguments are used.

The sapgui_open_connection_ex function opens a connection to the server defined by the connection_string. The function sets the output parameter connection_id. This parameter is used in sapgui_select_active_connection.

sapgui_open_connection_ex should be followed by sapgui_logon.

## Return Values

This function returns LR_PASS (0) on success or LR_FAIL (1) on failure.

Note: If a logon or connection in a script fails, the script replay is aborted. You can allow the script replay to continue despite a failed logon or connection by enabling the following setting in the runtime settings: SAPGUI > General > Advanced > Disable abort on logon/connection.

## Parameterization

You can parameterize all string (char type) arguments.

## Example

The following example uses sapgui_open_connection_ex to initialize the channel to the R/3 server.

Copy code

    Action() {
    // Connect to R/3 server, and log on
    sapgui_open_connection_ex (
        ConnectionString="/SAP_CODEPAGE=1100 /FULLMENU myServer 00 /3",
         Description="MYSERVER",
         ConnectionID="con[0]")
    sapgui_select_active_connection("con[0]");
    sapgui_select_active_session("ses[0]");
    sapgui_select_active_window("wnd[0]");
    // logging on as MyUserName
    sapgui_logon("MyUserName", "MyPassword", "800", "EN", LAST );
