 ## Localize error messages used in business rules
 
  If you have more than one language provisioned for your organization, you will want to localize any error messages that you have set. Each time you set a message, a label is generated by the system. If you export the translations in your organization, you can add localized versions of your messages and then import those labels back into the Dataverse, so that people using languages other than your base language can view the translated messages.
