PO Smartform as mail attachment

Hi All,

We would like to send PO smartform to the Buyer as mail attachment at the time of releasing PO. User can release PO using ME29N as well as ME28 transaction codes. We tried BADi ME_PROCESS_PO_CUST but it is getting called only when user releases PO using ME29N Tcode. Is there any configuration for directly sending the smartform as pdf attachment through mail?

Regards,

Sibin
