To localize a Cognos report, the Report Studio locale must be set to "en_ZW" before authoring a report. Cognos reports reference localized data source and column names based on the Report Studio locale. Any change to these data source and column names for this locale will result in not being able to look up the translated text in another locale. The official workaround recommended by Cognos is to use non-volatile names in a special locale. This special locale is "en_ZW".
