How to delete .pdf file after viewing in SAP

Question

Hi,
I've a program to show a pdf file within a SAP window using the open document method form the class cl_gui_pdfviewer. Now I want to delete the pdf file once I choose the back button or exit the program. How can I do that.
In the PAI for the screen showing the pdf file, I have a case statement to perform the following
  When 'EXIT'
     call method my_pdf_viewer->close_document.
        .....    <--- some coding to try deleting the pdf file
     leave program.
endcase.
It seems that the pdf file is still in use by the program and cannot be deleted before leaving the program. Please help.
Thanks in advance,
Francis

Hi All,
I have had this issue and have finally resolved it.  Here's how:
you need to destroy your custom container and html viewer control AND flush the front end cache.  This releases the lock on the file and lets you then delete it.
Here's an example code:
When 'EXIT'
call method my_pdf_viewer->close_document.
  CALL METHOD my_pdf_viewer->FREE
    EXCEPTIONS
      CNTL_ERROR        = 1
      CNTL_SYSTEM_ERROR = 2
      others            = 3
  IF SY-SUBRC is initial.
    free my_pdf_viewer.
  ENDIF.
this is the custom control parent container that contains the html control
  CALL METHOD MY_CONTAINER->FREE
     EXCEPTIONS
       CNTL_ERROR        = 1
       CNTL_SYSTEM_ERROR = 2
       others            = 3
  IF SY-SUBRC is initial.
    free my_container.
  ENDIF.
  CALL METHOD cl_gui_cfw=>dispatch.
  CALL METHOD cl_gui_cfw=>flush
        EXCEPTIONS CNTL_SYSTEM_ERROR = 1
        CNTL_ERROR = 2.
... <---- Delete PDF file (Delete Dataset xxxxxx.pdf)
leave program.
endcase.
The other issue brought up is probably a permission issue -- trying to read the file from the presentation server versus a mapped drive that the SAP backend can access.  I read pdf files from a shared drive that the SAP backend can read/write to and it picks it up and displays just fine.
