hi Reddy

Thanks for your help.

I readed that blog and copy the code into my abap editor.

When I put the value 'T001',it worked well,

but when 'KNA1',I saw a short dump(System error).

In Unicode System, the method "cl_alv_table_create=>create_dynamic_table " is OK?

Hello Chen

You may have a look at thread

If you have RTTI available on your SAP system I would go for it.

Hi,

Check this sample code,

DATA:
  o_ref TYPE REF TO data.
FIELD-SYMBOLS:
  <lt_table> TYPE STANDARD TABLE,
  <fs>       TYPE ANY,
  <field>    TYPE ANY,
  <field1>   TYPE ANY.
PARAMETERS:
  p_tab       TYPE tabname default 'MARA', " Table name (eg: MARA)
  p_field(20) TYPE c default 'MATNR'.      " Field name (eg: MATNR)

START-OF-SELECTION.
  CREATE DATA o_ref TYPE TABLE OF (p_tab).

  ASSIGN p_field TO <field1>.
  ASSIGN o_ref->* TO <lt_table>.

  SELECT *
    INTO TABLE <lt_table>
    FROM (p_tab).

  LOOP AT <lt_table> ASSIGNING <fs>.
    ASSIGN COMPONENT <field1> OF STRUCTURE <fs>
                  TO <field>.
    IF sy-subrc = 0.
      WRITE:/ <field>.
    ENDIF.
  ENDLOOP.

Do like this.

REPORT  z_test                                .

TYPE-POOLS: slis.

DATA: it_fieldcat TYPE lvc_t_fcat,
      is_fieldcat LIKE LINE OF it_fieldcat.

DATA: new_table TYPE REF TO data.

DATA: new_line TYPE REF TO data.

FIELD-SYMBOLS: <l_table> TYPE ANY TABLE,
               <l_line>  TYPE ANY,
               <l_field> TYPE ANY.


PARAMETERS: p_table TYPE dd02l-tabname.

* Build fieldcat
CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
  EXPORTING
    i_structure_name = p_table
  CHANGING
    ct_fieldcat      = it_fieldcat[].


* Create a new Table
CALL METHOD cl_alv_table_create=>create_dynamic_table
  EXPORTING
    it_fieldcatalog = it_fieldcat
  IMPORTING
    ep_table        = new_table.

ASSIGN new_table->* TO <l_table>.

* Create Work Area
CREATE DATA new_line LIKE LINE OF <l_table>.
ASSIGN new_line->* TO <l_line>.
