title: Sending email to a SAP inbox and an ordinary email inbox
body: <p>I needed a function to send an email to an ordinary email address and to send on too to an SAP Inbox. I found this function:</p>
  
  <pre><code>CALL FUNCTION 'SO_NEW_DOCUMENT_ATT_SEND_API1'
              EXPORTING
                document_data              = gd_doc_data
                put_in_outbox              = 'X'
                commit_work                = 'X'
              TABLES
                packing_list               = it_packing_list
                contents_txt               = it_message
                receivers                  = it_receivers
              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.
  </code></pre>
  
  <p>The it_receivers it's filled like this:</p>
  
  <pre><code> FREE wa_it_receivers.
          wa_it_receivers-receiver   = sy-uname.  "&amp;----- Assign SAP User Id
          wa_it_receivers-rec_type   = 'B'.                    "&amp;-- Send to SAP Inbox
          wa_it_receivers-com_type   = 'INT'.
          wa_it_receivers-notif_del  = 'X'.
          wa_it_receivers-notif_ndel = 'X'.
          APPEND wa_it_receivers TO it_receivers .
  </code></pre>
  
  <p>This only send's the email to the SAP inbox. I went to the domain of the rec_type field to see which letter is so it can send the email to an ordinary email account. I believe it is 'A' but, as it only says external address. Is that the one? Thank you.</p>
