Hi Ajit,
It is always a good idea to create a specific enum for specific purposes. Translating one enum to another can easily be done in a rule.
When the specs for your app change in the future, or Mendix changes the system enum, you will only have to change the translation-rule instead of changing all your microflows and migrate your database.
For now a little bit more work but it leaves you with a more robust and better maintainable app.
Best regards,
