How to switch between Development and Production servers when using Enterprise Gateways?

Anonymous Thanks for sharing the link, I still din't try what you shared as Cherry's solution was closer to what I was trying to achieve.

v-piga-msft Cherry, Thanks for sharing the blog!

I was able to partially reproduce what was given in the blog. I am missing something here to get the actual results.

Let me give my scenario:

- I have just 1 dataset in Power BI Desktop. I want to use this same dataset to create reports and switch from development to production. 

- Used Import connection.

- No SQL Statement since I am connecting to just 1 table directly.

- I have created 1 parameter for Server Name where the 'Current Value' is having Development Server information.

- I have created 1 parameter for Database Name which should be the same for production.

1) Should I create another Parameter with Production Server information?

2) Even if I publish with 2 parameters (Dev and Prod), all I can see only the parameter which was selected, saved and published through Power BI Desktop. 

I cannot change the Parameter in Power BI Service.

3) Where should I declare the @@ServerName, since I am not using the SQL Statement instead have imported the table?

Thanks again!
