Standard CDS Views that have "Privileged Access" as primary datasource to build a Custom CDS View and when trying to preview data it's empty and returning the message "No Data". 

SAP S/4HANA Cloud Public Edition

1. Open Custom CDS Views.
2. Search for the documented views.
3. Click 'Preview Data' button.
4. No data will display.

• Custom CDS View inherits its protection exclusively from its primary data source. 
• Custom CDS view has the status privileged only, the data contained can't be accessed directly and cannot be exposed as an external API.
• Such views are primarily intended to be used as associated Data Sources in other CDS views.

1. Open the application "Custom CDS Views".
2. Choose a primary datasource for the Custom CDS View and use the view with privileged access as an association datasource.
3. Perform a Join Condition.
