SO_NEW_DOCUMENT_SEND_API1 not working
I am using FM SO_NEW_DOCUMENT_SEND_API1 to send mail to the external user but it is showing in waiting state in my outbox.When i execute the FM sy-subrc is 0, suggesting FM executed correctly and i can see the mail in my outbox as well in waiting status showing message Wait for communications service but i am not able to see the mail in SOST in queue.I tried with program rsconn01 with following code.
SUBMIT rsconn01 USING SELECTION-SET 'INTERNET-EMAIL' AND RETURN.
*CALL FUNCTION 'SO_DEQUEUE_UPDATE_LOCKS'.
but still its not working.
