Hi Richa Tripathi,
You may consider the following customising:
> output determination
> simple mail (medium 7)
> output condition (VV11)
> to "Send immediately(when saving the application)" to a mailing partner
> (MP) which points to a distribution list.
> SO01
Above is only a guideline please consider the 'send immediately (when saving the application)"' function
in order to send notification through email to the customer.
Thanks.
Best Regards,
Simon
