Hi @suryanarayana Have you read through this article on localization? I think it addresses some/all of your questions.

Hi @lila_meyer  yup i have gone through document and after trying to set it up then i got few doubts which i posted .

Hi suryanarayana ,

Here are the answers to your queries

1. Actually, it’s the other way round. You must first configure the create and custom attribute and only then you can use it in engagements.
   
   If you wish to use custom attributes as the method to identify User’s local language, you must first create a new custom attribute in User object. This attribute must be such that all its values must be language codes supported in PX. Once the custom attribute is created, you must select this attribute as the local language identifier in the Localization admin page. This attribute is included in the identify call and when a user logs in to the application, the language code in the Identify call helps PX identify the local language of the user. You can find a detailed explanation of this in the Configure Localization section of the aforementioned doc.
    
2.  Yes. Translation must be performed manually and uploaded through the XLIFF file.
3. We do not authenticate the accuracy of translation. we only support translation. user needs to ensure that the translated content is accurate. 

      Hope your queries are resolved. Please feel free to revert, if you have any further queries. 

Regards

Prashant
