Overview of All Predefined Dictionary Types
The following tables show the predefined types in ABAP Dictionary and their fundamental technical attributes. For each predefined data type in ABAP Dictionary, the last column specifies the predefined ABAP type to which the predefined type is mapped in type references from an ABAP program to ABAP Dictionary. An initial value is assigned to most predefined data types. These initial values are applied when initial dynpro fields are displayed and when database fields are initialized.
