ABAP CREATE OBJECT PARA TABLES Statement syntax and functionality in SAP

CREATE OBJECT - parameter_tables

Short Reference

ABAP Syntax ... [PARAMETER-TABLE ptab]
[EXCEPTION-TABLE etab].

What does it do? The PARAMETER-TABLE and EXCEPTION-TABLE additions pass actual parameters dynamically to the instance constructor or assign return codes to the non-class-based exceptions.
These additions can be used only if the instantiated class is specified dynamically in name . Using the special internal tables ptab and etab , they assign actual parameters to the input parameters of the instance constructor, or return codes to the non-class-based exceptions.
The syntax and semantics are the same as those that apply to dynamic method calls using the statement
CALLMETHOD . The internal tables ptab and etab in particular must be defined with reference to the tables
ABAP_PARMBIND_TAB and ABAP_EXCPBIND_TAB from the type group ABAP.

Example ABAP Coding The following example illustrates how a dialog box of Control Framework ( CFW
) is generated dynamically and how input parameters are passed dynamically to the instance constructor of the global class
CL_GUI_DIALOGBOX_CONTAINER . The class is defined explicitly using the
TYPE addition.
DATA: container TYPE REF TO cl_gui_container,
exc_ref TYPE REF TO cx_root.

DATA: class TYPE string VALUE `CL_GUI_DIALOGBOX_CONTAINER`,
ptab TYPE abap_parmbind_tab.

ptab = VALUE #( ( name = 'PARENT'
kind = cl_abap_objectdescr=>exporting
value = REF #( cl_gui_container=>desktop ) )
( name = 'WIDTH'
kind = cl_abap_objectdescr=>exporting
value = REF #( 1000 ) )
( name = 'HEIGHT'
kind = cl_abap_objectdescr=>exporting
value = REF #( 300 ) ) ).

TRY.
CREATE OBJECT container TYPE (class)
PARAMETER-TABLE ptab.
CATCH cx_sy_create_object_error INTO exc_ref.
MESSAGE exc_ref->get_text( ) TYPE 'I'.
ENDTRY.
