ABAP CREATE DATA HANDLE Statement syntax, information and example SAP source code

CREATE DATA - HANDLE

Short Reference

ABAP Syntax_6 CREATE DATA dref [
area_handle ]
TYPE HANDLE handle.

What does it do? The statement CREATE DATA uses the addition
HANDLE to create a data object whose data type is described by an RTTS type description object . For handle , a reference variable of the static type of class CL_ABAP_DATADESCR
or its subclasses has to be specified, which points to a type description object. The type description object object may have been created using the RTTS methods on existing data objects, or using the dynamic definition of a new data type.
The type description object must describe a non-generic type. Only type description objects for the generic ABAP types c , n , p , and x create and use a new bound data type with the standard values . Similarly, a type description object for a standard table with a generic table type creates and uses a new bound table type with a standard key.

Latest notes: Important methods for the dynamic definition of data types are:
GET_C , GET_D , GET_F ... of the class CL_ABAP_ELEMDESCR for type description objects of elementary data types. Either a new type description object is created in accordance with the input parameters or an existing type object is reused.

GET of the classes
CL_ABAP_STRUCTDESCR ,
CL_ABAP_TABLEDESCR , and
CL_ABAP_REFDESCR plus GET_BY_NAME of the class CL_ABAP_REFDESCR for type description objects of structures, internal tables, and reference variables. These methods return the type description object that was specified using the input parameters. A new type description object is generated or an existing one is used again.

CREATE of the classes
CL_ABAP_STRUCTDESCR ,
CL_ABAP_TABLEDESCR , and
CL_ABAP_REFDESCR for creating type description objects for structures, internal tables, and reference variables. These methods return the type description object that was specified using the input parameters. A new type description object is always created.

Latest notes: We recommend using the GET methods instead of
CREATE to avoid creating multiple type description objects for a single type.
