- Table Types

A DDIC table type defines the data type of an internal table in ABAP. The DDIC table type defines the following in an internal table:

• Line type

• The table category

• The table key

A program-internal object declared with reference to a table type is an internal table of this type.

• Technical attributes of table types

• Semantic attributes of table types

Notes

• Unlike in data elements and DDIC structures, the DDIC table types exist only to create globally visible definitions of internal tables. DDIC table types replace the definition of internal tables in type pools and can themselves be replaced using the declaration of internal table types in global classes and interfaces (if the context where the type is required is suitable). The attributes of an internal table that can be defined in the ABAP Dictionary match those that can be specified using the statement TYPES ... TABLE OF in ABAP programs completely. For more information, see the in-depth documentation about internal tables in the ABAP programming language.

• The name of a table type must follow the naming rules for DDIC data types.

Example

The table type SPFLI_KEY_TAB describes a hashed table with the structured line type SPFLI with a unique primary key and two non-unique secondary table keys.
