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:
CALL FUNCTION 'SO_NEW_DOCUMENT_ATT_SEND_API1'
document_data = gd_doc_data
put_in_outbox = 'X'
commit_work = 'X'
packing_list = it_packing_list
contents_txt = it_message
receivers = it_receivers
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.
The it_receivers it's filled like this:
wa_it_receivers-receiver = sy-uname. "&----- Assign SAP User Id
wa_it_receivers-rec_type = 'B'. "&-- 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 .
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.
Here you have a nice example of how to do it wiki.sdn.sap.com
I don't know why people keep on digging up that old function module. I'd always recommend using the Business Communication Services API - it's well documented and much easier to use. The docs also contain an example on how to send to an external mail address.
