Solution

Hi,

Reactive Web App doesn't have preparation, you have to use the option "Fetch Data from the Database".

For adding new screens you must go to the Interface tab. 

Hope it helps :).

Hi Muhamed,

Yes, those options (fetch from database and fetch from other sources) are similar but they also have some differences.

You might be following the courses for Traditional Web, and it looks you are creating a Reactive Web app. You should either start learning Reactive Web (if you are only going to work in new projects) or continue the training but select the "Traditional Web App" option when creating an app (if you are going to work in existing OutSystems projects that are built with traditional web). Reactive Web apps were introduced last month and they are a new way to create web applications in OutSystems.
