F.61 Should Send Email (PDF attachement) after printing it

Hi ,

I am an abaper and i have a requirement to trigger a mail automatically to customer for both credit memo(SAP11) and customer invoice (SAP19) in F.61 Tcode after printing. I create Correspondence request in FB12 and in F.61 i print it .But i need to trigger email to customer with invoice / credit memo as a pdf attachment automatically . Is that possible with configuration alone or do i need to create a custom program using standard reference??

Thanks in advance..

Thanks,
Srini
