Summary

Structure is a group of internal fields that logically belong together. A Structure consists of components (fields) whose types are defined.

Substructures allow you to include fields from another table or structure in the table you are creating.

Customizing includes are provided in SAP tables and structures to allow you to add fields to these structures/tables without modifying the tables themselves.

Append structures allow you to add fields to SAP-provided structures and transparent tables that were not provided for in the standard version.
