Table Types

- The table category
- The table key
An internal program object declared with reference to a table type is an internal table of this type.
Other versions:
7.31 | 7.40 | 7.54
Note
Unlike in data elements and
structures, the table types in ABAP Dictionary exist only to create globally visible definitions of internal tables. Table types replace the definition of internal tables in
type groups 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
ABAP Dictionary match in full those that can be specified using the statement
TYPES ... TABLE OF in ABAP programs. More information can be found in the in-depth documentation about internal tables in ABAP - Reference.
Example
The table type SPFLI_KEY_TAB describes a hashed table with the structured row type SPFLI with a unique primary key and two non-unique secondary table keys.
