Thank you for the detailed description. Do you know where these language settings are being stored? I would like to roll out the SAP GUI with a predefined language setting, and I'm hoping there is somewhere a configuration file for this.

Hello Yoann, Sorry, I couldn't make it work. Unfortunately, the description regarding the code page section in Note 99435 is not very specific, and doesn't provide an example. -1 = default code page is used: 1100 0 to nn = index on the language ID according to the sequence in the selection box in the extended dialog in SAPlogon. I tried different values. But all I got was a SAP System Message invalid GUI connect data error message.
