Data present in internal table, now how to open it in PDF format

Question

Dear Friends,
my Scenario is..
I have uploaded a pdf file in my database table through  GUI_UPLOAD. It is uploaded.
Now when user click on some button then that file should be displayed again in pdf format directly.
(No download to user PC using GUI_download or something)
DBtab ZTST_XL Format
MANDT     MANDT     CLNT     3
KEYA     CHAR5     CHAR     5
KEY2     INT4     INT4     10
LENGTH     INT2     INT2     5
DATA          LCHR     1000
I brought that data again in my internal table by 
SELECT * FROM ZTST_XL
    INTO TABLE DBTAB
    WHERE KEYA = 'TEST'.
  LOOP AT DBTAB.
    ITAB-DATA = DBTAB-DATA.
    APPEND ITAB.
  ENDLOOP.
Now I need to open this PDF file in normal format as it opens usually rather than downloading it on users PC .
Any Help regarding this will be very much useful
Thanks & Regards,
Sourabh

So you just want to show the PDF file you have uploaded to the DB on click of the 2nd button.
Now you can use the method CL_GUI_FRONTEND_SERVICES=>EXECUTE for this after the user clicks the 2nd button
CALL METHOD cl_gui_frontend_services=>execute
      EXPORTING
        DOCUMENT              = lv_document "The filepath you have used for GUI_UPLOAD
      EXCEPTIONS
        cntl_error             = 1
        error_no_gui           = 2
        bad_parameter          = 3
        file_not_found         = 4
        path_not_found         = 5
        file_extension_unknown = 6
        error_execute_failed   = 7
        synchronous_failed     = 8
        not_supported_by_gui   = 9
        OTHERS                 = 10.
Hope i am clear.
BR,
Suhas
