This example screen from SAP Core Banking has the Program Hierarchy with tree nodes showing Components, Programs, transactions and tables.  One of the tables is expanded on the right of the screenshot.

How does Saphir extract this information?

Saphir extracts metadata from the ABAP Data Dictionary using an ABAP Function that Saphir invokes using SAP RFC calls.

By utilising the Data Dictionary access tables Saphir captures all the tables exactly as implemented, including Z tables.
