Fileld Symbols

Question

Hi All,
Iam creating a structure and table dynamically as below.
**filed symbols
FIELD-SYMBOLS: <table> TYPE table,
               <row> TYPE data.
struct_type = cl_abap_structdescr=>create( comp_tab ).
  struct_type = node_info->get_static_attributes_type( ).
  table_type = cl_abap_tabledescr=>create( p_line_type = struct_type ).
  CREATE DATA my_table TYPE HANDLE table_type.
  ASSIGN my_table->* TO <table>.
  CREATE DATA my_row TYPE HANDLE struct_type.
  ASSIGN my_row->* TO <row>.
Now in runtime I would be able to see the structure of <table> and <row> and also the data if it has. My problem is how would I read that data in to an internal table.
For example if the table has structure of 5 columns how would i read 5th column?
I would like to overwrite the content of 5th column with the content of 4th column.
is it possible? If it is please help me out.
Thank You,
Suresh.

Hi Suresh,
    I had same requirements where I had ti fill table with plants.
Check out for the code snippet. And reward points if its helpful.
Code:
method FILL_PLANT .
types : begin of str_cost,
          kostl type zcostcenter-kostl ,
        end of str_cost.
types : begin of str_ekgrp,
          ekgrp type zekgrp-ekgrp,
       end of str_ekgrp.
data  :  itab_cost type table of str_cost with default key .
data  : itab_ekgrp type table of str_ekgrp with default key.
data : wa_mara type str_cost.
data :  lt_attributes type  If_Request_Ior=>Elements_Plantnode,
         wa_attributes type If_Request_Ior=>Element_Plantnode.
field-symbols : <fs_cost> type str_cost.
CALL FUNCTION 'ZPD_RFC_COSTCENTER' DESTINATION 'tr3_clnt800'
  TABLES    IT_COST  = itab_cost.
CALL FUNCTION 'ZPD_RFC_PURGROUP' DESTINATION 'tr3_clnt800'
TABLES IT_EKGRP  = itab_ekgrp .
loop at itab_cost assigning <fs_cost> .
      wa_attributes-plant = <fs_cost>-kostl.
      insert wa_attributes into table lt_attributes.
endloop.
  node->bind_elements( lt_attributes ).
endmethod.
Hope this will help you.

Darshna.
