Hi

What is the difference between a Substructure and an Append Structure

[former_member235056]

Hi frend,

The difference lies nowhere but in the way the structures are availed to tables such that one structure may contain many substructures in it but one table may contain append structure linked to only one table.

Substructures are created before anytime and included in the table whereas append structure is created from within the table and is linked to that table only.

HI

- In case of a substructure, the reference originates in the table itself, in the forma of a statement .include... .

-In case of an append structure, the table itself remains unchanged and the reference originates in the append structure.

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

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