hi sky ,
  use dynamic table as:-
  Declaration for Dynamic Table:-
FIELD-SYMBOLS: <dyn_table>  TYPE STANDARD TABLE,
               <dyn_table1> TYPE STANDARD TABLE,
               <dyn_wa1>,
               <dyn_wa>.
FIELD-SYMBOLS: <l_fs_dyn> TYPE ANY,
               <l_fs_bom> TYPE ANY.
*---Dynamic Internal Table
DATA: dy_table            TYPE REF TO data,
      dy_table1           TYPE REF TO data,
      dy_line             TYPE REF TO data.
Creation of Dynamic Internal Table:-
  CALL METHOD cl_alv_table_create=>create_dynamic_table
       EXPORTING
         it_fieldcatalog = fcat  (for which internal table needs to be built)
       IMPORTING
         ep_table = dy_table
       EXCEPTIONS
         generate_subpool_dir_full = 1
         OTHERS = 2
  IF sy-subrc <> 0.
  ENDIF.
Population of Dynamic Internal Table:-
CLEAR: l_tabix,
       w_tabix.
  ASSIGN dy_table->* TO <dyn_table>.
  CREATE DATA dy_line LIKE LINE OF <dyn_table>.
  ASSIGN dy_line->* TO <dyn_wa>.
  ASSIGN dy_table->* TO <dyn_table1>.
  CREATE DATA dy_line LIKE LINE OF <dyn_table1>.
  ASSIGN dy_line->* TO <dyn_wa1>.
   LOOP AT it_parent.
    l_tabix = sy-tabix.
    LOOP AT fcat INTO ls_fcat TO 23."WHERE col_pos <= '19'.
        ASSIGN COMPONENT ls_fcat-fieldname
            OF STRUCTURE <dyn_wa> TO <l_fs_dyn>.
        ASSIGN COMPONENT ls_fcat-fieldname
            OF STRUCTURE it_parent TO <l_fs_bom>.
        <l_fs_dyn> = <l_fs_bom>.
      ENDIF.
    ENDLOOP
