Creating or adding a data service in the Repository
In App Builder, there are two starting points from which you can create or
add a data service for a project: You can add it first into the App Builder Repository and
then import it from there into your project, or you can add it directly into your project.
If you add the data service first into the App Builder Repository, it is initially saved only to the Repository. If you then want to use it in your project, you can import it to your project from the Repository.
If you add the data service directly to your project, it is saved only as part of your project. If you later decide to put it into the App Builder Repository, you must first export it from your project as a file and then import that file into the Repository. In the case of adding a data service by file import, however, you might be able to simply import the same data service file from the same source you imported it into your project.
