How to populate dynamic internal table fields with data??

Question

Hi Folks,
How to assign a particular internal table field to a dynamically assigned internal table?
I have an excel sheet, and i upload the excel sheet data into an internal IT_EXLOAD table using FM ALSM_EXCEL_TO_INTERNAL_TABLE
Now i created a dynamic internal table which has the same column as in my DB table.
I have to fill the dynamically created Internal table with the IT_EXLOAD data dynamically.
Suppose in future if i add some field in DB table and for that field if i add some column in excel sheet there is no need to change in the program.
Looking for reply...
Best Regards,
Sayak

hi,
CALL FUNCTION 'ALSM_EXCEL_TO_INTERNAL_TABLE'
       EXPORTING
            filename                = p_path
            i_begin_col             = '1'
            i_begin_row             = '2'
            i_end_col               = '2'
            i_end_row               = '1000'
       TABLES
            intern                  = intern
       EXCEPTIONS
            inconsistent_parameters = 1
            upload_ole              = 2
            OTHERS                  = 3.
*declare intern_tmp as internal table tb_data in wich you want the data
*and declare a field symbol <fs_123>
LOOP AT intern.
    ASSIGN COMPONENT intern-col OF STRUCTURE
    intern_tmp TO <fs_123>.
    IF NOT <fs_123> IS ASSIGNED.
      CLEAR intern.
      CLEAR intern_tmp.
      CONTINUE.
    ENDIF.
    <fs_123> = intern-value.
    AT END OF row.
      CLEAR tb_data.
      MOVE-CORRESPONDING: intern_tmp TO tb_data.
      APPEND tb_data.
      CLEAR intern_tmp.
    ENDAT.
    CLEAR intern.
  ENDLOOP.
**paste this code and you can see the data in ur tables dynamically.
