How to: Add a New or Existing Report to a Report Project (SSRS)
In Business Intelligence Development Studio, you can add a new report by using the Report Wizard or by adding a new blank report to your project. You can also add an existing report. After you add a report, you can see the report name listed under the Reports folder in your project.
Note
To preview a report with existing data sources, you must have permissions to the data source from your report authoring client. For more information, see How to: Create an Embedded or Shared Data Source (SSRS).
After you add a report, you can define data sources, datasets, and design a report layout. To get started, see Tutorial: Creating a Basic Table Report (SSRS) or Adding a Table (Report Builder 3.0 and SSRS).
