如何通过SAP GUI Scripting设置连接语言？寻找对应Set方法

Great question! Let's tackle this for you—since SAP GUI Scripting docs can be scattered, it’s totally understandable to hit this roadblock. First off, you’re right: Session.Info.Language is a read-only property with no built-in Set method. It only reflects the current session’s language, not something you can directly modify via that property. But don’t worry, there are two reliable ways to set or switch the language in your script:

1. Set Language When Opening the Connection #

The cleanest approach is to specify the language before the session loads, using a connection string that includes the language parameter. This ensures your session starts in the desired language right away, no mid-script resets needed.

Here’s how to do it in VBScript with OpenConnectionByConnectionString:

Dim Application As Object 'GuiApplication
Dim Connection As Object 'GuiConnection
Dim Session As Object 'GuiSession

Set Application = GetObject("SAPGUI").GetScriptingEngine

' Build your connection string with the LANG parameter (use EN for English)
Dim connString As String
connString = "DES=YourSystemName;ASHOST=your.sap.server;SYSNR=00;CLIENT=100;LANG=EN"

' Open the connection with the specified language
Set Connection = Application.OpenConnectionByConnectionString(connString, True)
Set Session = Connection.Sessions(0)

' Verify the language is set correctly
MsgBox Session.Info.Language ' Should return "EN"

Just replace the placeholder values (like YourSystemName, your.sap.server) with your actual SAP system details.

2. Switch Language in an Existing Session #

If you already have an active session and need to switch languages mid-script, you can use SAP’s native language switch command. This simulates entering the command in the SAP command bar and executing it.

⚠️ Note: This will reset your session (any unsaved work will be lost), so make sure to save data before running this.

VBScript example:

' Assume you already have an active Session object
' Enter the language switch command in the command bar
Session.findById("wnd[0]/tbar[0]/okcd").text = "/l EN"

' Execute the command (press Enter)
Session.findById("wnd[0]").sendVKey 0

' Wait for the session to reload, then re-reference the session
Set Session = Connection.Sessions(0)

' Verify the language change
MsgBox Session.Info.Language ' Should now return "EN"

The /l command is SAP’s standard language switch shortcut—replace EN with your target language code (e.g., DE for German, FR for French).

Key Notes #

• Session.Info.Language will never have a Set method because it’s designed to report the current session state, not modify it.
• Using the connection string method is preferred for automation workflows, as it avoids session resets and potential data loss.
• The language switch command requires your SAP user to have permission to change languages (most standard users do, but it’s worth checking if you run into issues).
