- Built-In Data Types

The built-in data types in ABAP Dictionary are used as follows:

• To construct self-defined data types (data elements, structures, including DDIC database tables and DDIC views, and table types) in the ABAP Dictionary. They can also be used in CDS DDL in ABAP CDS. With the exception of some type specifications in ABAP SQL they cannot be addressed directly in ABAP programs. Here, they can only be addressed by using dictionary objects or CDS objects and this is why they are also called external data types.

• They have special technical and semantic attributes that support modeling of semantic models.

• They represent an interface between the built-in ABAP types and all possible vendor-specific data types of the supported databases. A corresponding mapping takes place in both directions.

The following sections describe the attributes of the built-in data types in ABAP Dictionary:

• Overview of All Built-In Dictionary Types

• Properties of the Built-In Dictionary Types

• Use of the Built-In Dictionary Types
