When exporting a Terminology as TBX file from WorldServer, why the langId in TBX is inconsistent with the locale ID which are defined under Management > Business Rule Linkage > Locales?
 

Locale ID will change according to customer environment. However, exported TBX files use langId instead of the locale ID hence you will see the inconsistency of them.
Besides, langId of a specific language can be confirmed in the database table [dbo] [languages] [languageid] column on WS Database.
