Hi all,

I am trying to make the new language in Vietnamese by custom language tool in SAP 9.0.

I read the User guide but could not found the example to create the XML file for new language.

Here is my command typed but i have not done yet.

c:\CLT>CLT.exe create SBO_English ( United States).XML SBO_Vietnamese.XML VN 100009 Vietnamese (Vietnam) Vietnamese

The error is ""The Languages ID is not valid, exactly 2 characters are required

Please help or give me the document with example.
