ABAP_DDIC - Overview of All Built-In Dictionary Types The following tables show the built-in types in ABAP Dictionary and their fundamental technical properties. For each built-in data type in ABAP Dictionary, the last column specifies the built-in ABAP type to which the built-in dictionary type is mapped when used as type reference in an ABAP program. Most built-in dictionary types are assigned an initial value. These initial values are applied, for example, BEGIN_SECTION VERSION 5 OUT when initial dynpro fields are displayed, END_SECTION VERSION 5 OUT when database fields are initialized , and in the AB-SQL condition IS INITIAL. The initial value of ABAP Dictionary types is not used for data objects declared in ABAP programs when referring to these types. Here, the initial value of the mapped built-in ABAP types is used.
