CREATE DATA  Syntax Diagram

Short Reference

Syntax Forms



Defining the data type implicitly

1. CREATE DATA dref [area_handle].

Defining the data type using predefined ABAP types

2. CREATE DATA dref [area_handle]
                   TYPE {abap_type|(name)}
                        [LENGTH len] [DECIMALS dec].

Defining the data type using an existing type

3. CREATE DATA dref [area_handle]
                   { {TYPE [LINE OF] {type|(name)}}
                   | {LIKE [LINE OF] dobj}  }.

Creating data with reference to a type description object

4. CREATE DATA dref [area_handle]
                   TYPE HANDLE handle.

Creating reference variables

5. CREATE DATA dref [area_handle]
                  TYPE REF TO {type|(name)}.

Creating internal tables

6. CREATE DATA dref [area_handle]
                  { {TYPE [STANDARD]|SORTED|HASHED TABLE
                      OF [REF TO] {type|(name)}}
                   | {LIKE [STANDARD]|SORTED|HASHED TABLE OF dobj} }
                   [ {WITH [UNIQUE|NON-UNIQUE]
                           {KEY {comp1 comp2 ...}|(keytab)}|{DEFAULT KEY}}

                   | {WITH EMPTY KEY} ]
                   [INITIAL SIZE n].

Effect

The CREATE DATA statement creates an anonymous data object and assigns the reference to the data object of the dref reference variables.

By default, the data object is created in the internal session (heap) of the current program and remains there for as long as it is required. If no data references and no field symbols point to the data object or to a part of the data objects, it is deleted by Garbage Collector. The data object can be created as a shared object using the addition area_handle.

The reference variable dref must be declared as a data reference variable. The content of a data object that is created with CREATE DATA can only be accessed using dereferenced data variables or field symbols (see Data objects in operand positions).

The data type of the data object that is created can be defined using the TYPE addition and a type specification or with the LIKE addition and the specification of a data object. The syntax permits the dynamic definition of elementary data types, reference types, and table types. The HANDLE addition can reference any RTTS type description objects. According to the rules in section Assignments Between Data Reference Variables, the static type of the data reference variables has to be more general than the data type of the data object created, or be identical with it.

If a handleable exception is raised when the object is being created, the object is not created and the dref data reference variable retains its previous state.
