For this task to be successful:

Both the org where you issue the query and the org or cloud that you want to query are connected to Customer 360 Data Manager as data sources.
You have accepted the default mappings for both data sources or mapped the same entities and attributes as the default mappings.
You have configured both the DFS External Data Source and the DFS Named Credential.
You have connected a Commerce Cloud instance as a data source that has a working site with order data.
Replace SiteGenesis in the example with the name of your site.
