Change the Sitecore Language of a Sitecore Commerce 8.0 powered by Commerce Server and Commerce Server 11.2 Culture Mapping

Use the Commerce Server plug-in to change the language of a default culture

1. Create a new .config file in the Website\App_Config\Include directory of your Sitecore site.
   Note: The system applies the files in alphnumeric order. Ensure the file containing your overrides is named to run after CommerceServer.config, For example zzCommerceServer.config or My.Overrides.CommerceServer.config
2. Create a configuration section that overrides the culture attribute of a specific language.
   For example, the following configuration instructs the Commerce data providers to use the en-CA culture in the Commerce catalog system when the en language is selected in Sitecore (by default the en-US culture is used).

   <configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
     <sitecore>
       <commerceServer>
         <defaultLanguageCulture>
           <language name="en" culture="en-CA" patch:instead="language[@name='en']" />
         </defaultLanguageCulture>
       </commerceServer>
     </sitecore>
   </configuration>

3. Save and close the file
4. Restart IIS.
