Right-click the SAS connection you created and then select Retrieve Schema from the contextual menu.
A new wizard opens up where you can filter and show different objects (tables, views) in your database connection, select tables of interest, and define table schemas.
Filter databases objects according to your need, select one or more tables of interest, and modify the table schemas if needed. For details, see Retrieving table schemas.
When done, you can drag and drop any table schema of the SAS connection from the Repository tree view onto the design workspace as a new component or onto an existing component to reuse the metadata. For more information, see How to use centralized metadata in a Job and How to set a repository schema.
