You need to create the data source view for the StandardReports project. What should you do?

The Schema Generation wizard generates a relational schema from an existing SSAS model's dimensions and cubes - it is used after the model is built, not to create an initial DSV from a source database.

In SSAS, a Data Source View requires an underlying Data Source object that defines the connection string to the relational database. The correct workflow is to first create a Data Source pointing to the data warehouse, and then launch the Data Source View wizard, which uses that connection to allow selection of tables and views to include in the DSV. This two-step sequence is the standard SSAS project setup procedure.

The Import from Table wizard is used in SSAS Tabular models to import data, not to create a Data Source View in a Multidimensional project; this sequence conflates two different workflows.

A DSV cannot be created before a Data Source exists because it needs an active connection to enumerate available tables; the Import from Table wizard also does not apply to creating DSVs in Multidimensional projects.
