Shortly:

Append structures are used for enhancements that are not included in the standard. An append structure is a structure that is assigned to exactly one table or structure. There can be more than one append structure for a table or structure.

Includes are used to group fields, an include structure can be assigned to many tables. If you add a fields to an include structure, all tables/structures, which contain that include structure, will be updated too.

HI,

Basically APPEND structures are used to add additional fields to exactly one table, while CI may be used to include fields to several tables.

As far as I know there is no difference at the DB-level; as soon as either one is used the fields will be added at the end of the file (although an CI could be at any place in the Data Dictionary); of course with an exception in case one of the fields in de CI has been marked as Key-field.

Hope this is of any help.

append structure is one where for a table we use append structure and within this we implement the required fields along with its properties.....These are custom defined fields

include structure is one which is been appended to a table, but already the include structure has fields with its properties....These are SAP defined fields.
