Notification of creation and change of follow-on DOCs

Hi Experts,

I am implementing SRM 5.0 with ECC 5.0 in Classic Scenario.

I have a requirement for creating a e-mail notification for the requester user when the shopping cart follow-on documents are updated (e.g. PO created, PO changed in MM). The e-mail should include the PO number.

I already mapped these fields in the SC document on BBP_PD. Is there some BADI or report that can do this or should it be a separated development?

Thanks in advance,

Daniel
