ABENBUILT_IN_TYPES_COMPLETE - BUILT IN TYPES COMPLETE

Built-In ABAP Types

The following types are built-in in every ABAP program:

All built-in ABAP types from these tables are elementary and are included in the generic type simple. Apart from the types b and s, the built-in ABAP types can be used to define separate data types and data objects and for typing.

In addition to the actual built-in ABAP types, there is a predefined data type cursor that is global to the program, which currently has the same meaning as the built-in ABAP type i. It is required when declaring a cursor variable for database cursor handling.

Notes

• If no explicit start value is specified when creating a data object with one of the built-in ABAP types, the start value is set to the initial value specified for the relevant type.

• The built-in data types string and xstring describe data objects of variable length (dynamic data objects). While the length of data objects of all other elementary data types is fixed for their whole lifetime, the length of text strings and byte strings varies according to their content (the maximum size of a string is determined by the profile parameter ztta/max_memreq_MB, see Maximum Size of Dynamic Data Objects).
