Trigering of mail through FM

Hello All,

I'm using the FM SO_NEW_DOCUMENT_ATT_SEND_API1 to send a mail,but when I run the program it is not sending the mails directly.

But when I use the SUBMIT rsconn01 statement, the mails are sent.

Please let me know how to send mails without the SUBMIT statement.

Thanks in advance.

Best Regards

Jai
