Table Types

A table type describes the structure and functional attributes of an internal table in ABAP. In ABAP programs you can reference a table type TTYP defined in the ABAP Dictionary with the command DATA <inttab> TYPE TTYP. An internal table <inttab> is created in the program with the attributes defined for TTYP in the ABAP Dictionary.

A table type is defined by:

its line type, that defines the structure and data type attributes of a line of the internal table

the options for managing and accessing the data ( access mode) in the internal table

the key ( key definition and key category) of the internal table

The row type is defined by directly entering the data type, length and number of decimal places or by referencing a data element, structured type ( structure, table or view) or other table type. Or the row type can be a reference type.
