.ics calendar attachments sent from R/3

Question

Hi.
Does anyone know if it is possible to set the content type of a file attachment to an email sent from R/3?  Specifically, I need to set the content type to "text/calendar" when generating notifications from bsp that contain an MS Outlook calendar attachment (.ics file). 
When iCalendar attachments go through FM SO_DOCUMENT_SEND_API1, the content type is set to text/plain which apparently some virus scanners have a problem with. The virus scanner then corrupts the attachment.  The exact same attachment will work as an Outlook calendar entry if sent to a recipient with different virus scanner. 
Per RFC 2445, it appears content type should be text/calendar, but I can't find a manner to set this using R/3 functions for sending email...
Thanks for any help,
jason

Hi Jason,
just tested out FM SO_DOCUMENT_SEND_API1 in a small report. Find attached the coding that delivers a mail with the mime type you desire:
data:   ls_doc      like sodocchgi1,
        lt_content  type table of solisti1,
        wa_content  type solisti1,
        lt_rec      type table of somlreci1,
        wa_rec      type somlreci1,
        lv_int      type i,
        lv_int2     type i.
  wa_content = 'Line 1'.
  append wa_content to lt_content.
  wa_content = 'Line 2'.
  append wa_content to lt_content.
  wa_rec-receiver = '[email protected]'.
  wa_rec-rec_type = 'U'.
  append wa_rec to lt_rec.
* Mail Header
  ls_doc-obj_name = 'Test Mail Mime Type'.
  ls_doc-obj_descr = 'Mime Type test'.
  ls_doc-sensitivty = 'O'.
  describe table lt_content lines lv_int.
  lv_int2 = ( lv_int - 1 ) * 255.
  lv_int = strlen( wa_content ).
  lv_int2 = lv_int2 + lv_int.
  ls_doc-doc_size = lv_int2.
CALL FUNCTION 'SO_NEW_DOCUMENT_SEND_API1'
  EXPORTING
    document_data                    = ls_doc
    DOCUMENT_TYPE                    = 'ICS'
*   PUT_IN_OUTBOX                    = ' '
    COMMIT_WORK                      = 'X'
* IMPORTING
*   SENT_TO_ALL                      =
*   NEW_OBJECT_ID                    =
  tables
*   OBJECT_HEADER                    =
   OBJECT_CONTENT                   = lt_content
*   CONTENTS_HEX                     =
*   OBJECT_PARA                      =
*   OBJECT_PARB                      =
    receivers                        = lt_rec
EXCEPTIONS
   TOO_MANY_RECEIVERS               = 1
   DOCUMENT_NOT_SENT                = 2
   DOCUMENT_TYPE_NOT_EXIST          = 3
   OPERATION_NO_AUTHORIZATION       = 4
   PARAMETER_ERROR                  = 5
   X_ERROR                          = 6
   ENQUEUE_ERROR                    = 7
   OTHERS                           = 8
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
Here the relevant part of the mail header:
MIME-Version: 1.0
Importance: Normal
X-Priority: 3 (Normal)
X-Mailer: SAP Web Application Server 6.40
Content-Type: text/calendar;
charset="us-ascii";
method="VEVENT"
Content-Transfer-Encoding: quoted-printable
Content-Description: SAP.ics
I guess that's what you are looking for. Just adjust the receivers adress and test it out on your system.
Best Regards
Michael
