u can create dynamic table like this by using the fieldcatalog of ur previous internal table


******DATA DECLARATION*****************************

FIELD-SYMBOLS : <it_final> TYPE STANDARD TABLE,
                <wa_final> TYPE ANY,
                <w_field> TYPE ANY.


********CREATE DYNAMIC TABLE************************

  CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog           = it_fieldcatalog
    IMPORTING
      ep_table                  = new_table
    EXCEPTIONS
      generate_subpool_dir_full = 1
      OTHERS                    = 2.
  IF sy-subrc <> 0.
*  MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*             WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.

  ASSIGN new_table->* TO <it_final>.

*********CREATE WORK AREA****************************

CREATE DATA new_line LIKE LINE OF <it_final>.
  ASSIGN new_line->* TO <wa_final>.

*********INSERTTING WORK AREAR TO INTERNAL TABLE******

    INSERT <wa_final> INTO TABLE <it_final>.

*******POPULATING DATA*******************************  
  LOOP.
   
   ASSIGN COMPONENT 'FIELD1' OF STRUCTURE <wa_final> TO <w_field>.
   <w_field> = '12345'.

    ASSIGN COMPONENT 'FIELD2' OF STRUCTURE <wa_final> TO <w_field>.
   <w_field> = '21453DD'.

   FIELD1 AND FIELD2 ARE COMPONENTS OF FIELDCATALOG.
    
ENDLOOP.      

  ENDLOOP.
