Power BI also allows the creation of new reports from existing datasets. This brings up an identical interface to the one that appears when we're editing a report, except with a blank report canvas. To access this interface, simply click on the dataset in the Navigation pane. Clicking on this dataset presents you with a screen similar to the following screenshot:

Using this interface to create a new report is strikingly similar to creating a report in the Desktop. Like editing a report in the Service, there is no access to the underlying data, data model, or relationships, but otherwise, the experience is nearly identical.

Creating a new report is analogous to creating a new PBIX file in the Desktop, meaning that the report pages that are created here are not associated with the report pages that were originally published to the Service. This means that, once you create a new report in the Service, if you use the Download report option on the original report, the new report pages that were created will not be included.

Importantly, however, both the original report and the newly created report use the same underlying dataset. This is very different than in the Desktop, where each PBIX file contains its own data model and data (when not using a live connection). This makes the ability to create new reports in the Service a powerful feature as the data model can be created in the Desktop and published to the Service. Then, the Service can be used to create multiple reports from the same underlying dataset.
