SAP Inbound email related query (from Outlook to SAP)

Question

Hi,
I am in a situation where I have to send email from MS Outlook to SAP with a PDF file as an attachment. The PDF file will be stripped into an XML file and processed further and a reply is sent to the user sending the email. The Outlook admins have set up the necessary config for the connectivity - I am able to send the PDF file from Outlook to SAP (everything has been configured using SICF, SCOT etc) for inbound processing. In SCOT - Settings->Inbound processing I have used a Class which implements interface IF_INBOUND_EXIT_BCS (as per one of the blogs by Jeff Gebo). I can see the trace file in SCOT ->Utilities->Trace->Internal trace. When I send the PDF file, I can see in the trace (I cannot debug as the SAPCONNECT user which gets called in the backgound triggers the user exit class). In the trace file I can see my class gets instantiated but the next step to read the PDF file fails.  The code come the Jeff's blog which I use is as follows:
Set return code so that no other Inbound Exist class will be called
e_retcode = IF_INBOUND_EXIT_BCS=>gc_terminate.
try.
Get the email document that was sent.
  data: document type ref to if_document_bcs.
  document = io_sreq->get_document( ).
Get the sender's address to reply back
  lv_sender = io_sreq->get_sender( ).
  addr = lv_sender->address_string( ).
  return_addr = addr.
Get the interactive form attachment.
  data: pdf_table type BCSS_DBPC.
  pdf_table = document->get_body_part_content( 2 ).
Convert the pdf table into an xstring.
  data: pdf_xstring type xstring,
        pdf_line type solix.
  clear pdf_xstring.
  loop at pdf_table-cont_hex into pdf_line.
    concatenate pdf_xstring pdf_line-line into pdf_xstring in byte mode.
  endloop.
Process the PDF form
  data: formxml type string.
  formxml = me->process_form( pdf = pdf_xstring ).
Here the contents of the pdf_table-cont_hex is blank (I used a table to populate the values). All I get in my Outlook inbox is a empty email with an empty subject from SAP (called by the instantiated class of the Interface)
The irony is that I setup the same procedure has been configured and setup in another totally different SAP system and everything works fine there - I did a comparision of both SAP systems and everything seems fine (config wise and user exit class wise) and  everything is identical. I have no clue as to why it works in one system and not in the other system.
If anyone has any pointers wit will be greatly appreciated as I am on a tight deadline - I have checked OSS but with no help.
Thanks in advance,
Ryan

You may be able to find more information by putting an infinite loop at the beginning of your user exit:
x = ' '.
while x = ' '.
x = ' '.
endwhile.
and then go into debugging via SM50 and set the x variable to break out of the loop.
This technique is useful debugging workflows and other code which you cannot get to directly by placing a break-point.
