Doing changes to the report dynamically

Question

hi
i am working on a report whichaccepts a report in selection screen and  finds 'upload' function module available in it and replaces this with 'gui_upload' function module.
i have written code for commenting the existing function module and creating new function module i.e. 'gui_upload'.
can anyone let me know how can i implement these changes in to the report that i pass in the selection screen.
i.e. how ca i write these changes to the report.
thanks in advance.

Hi,
Use the following logic.
PARAMETERS : p_prog  TYPE reposrc-progname. " Report Name
*Check for Program Name in TADIR
SELECT obj_name object
            INTO TABLE tb_tadir FROM tadir
            WHERE pgmid = 'R3TR'
              AND object = 'PROG'
              AND obj_name LIKE  p_prog.
Read the Program and Get all the Update/Modify or Insert Statement
*through which  Z Tables are Getting Updated Directly
      PERFORM read_program USING wa_tadir-obj_name.
FORM read_program  USING  wa_tadir-obj_name.
  REFRESH tb_text.
Read the Report/Program
  READ REPORT wa_tadir-obj_name INTO  tb_text.
  DESCRIBE TABLE  tb_text LINES w_lines.
  DO w_lines TIMES.
    w_index = sy-index.
Read the table and search for MODIFY , UPDATE and INSERT
    READ TABLE tb_text INTO wa_text INDEX sy-index.
    IF sy-subrc EQ 0.
      SHIFT wa_text-text LEFT DELETING LEADING space.
      SEARCH wa_text-text+0(6)  FOR 'UPLOAD'.
      IF sy-subrc EQ 0.
Here write a routine to Replace UPLoad with GUI_UPLOAD.       
      ENDIF.
    CLEAR wa_text.
  ENDDO.
ENDFORM.
