Available tables will show.
In the image the most right column is a custom m-code column showing the current row count of each table. Click in a cell of the Data column to see a preview of the content. Carfefully, a click on "Table" adds another query step.
C_ tables indicate transaction data, I_ tables interface data aka master data and header data.

Improve performance using odata URL modifications, eg
add "/I_DeliveryDocument" to the source URL and avoid evaluating other tables

odata v4.0 might not be supported in your HANA release, hence URL modifications are limited
URL length limitations depends on the browser and is about 2k characters
