Send 2 or more emails from 1 PO

Hi Friends,

I want to send 2 or more emails to vendor for different email addresses from one PO (this should be applicable to ME21N, ME22N or ME21, ME22). The standard PO program is sending only one email. In XK02, vendor is maintained with different email addresses. I researched forums but I couldn't find a clue on how to achieve this. Can some one please guide me to do this? Is there any sample code for achieving this? How is this possible for a SAP Script form?

Please help.

Thank you.
