Hi,
Business requirement is that a requisitioner should trigger a email after PO is saved, PO release, Goods Received, and Invoice Verification. At every stage requisitioner should get mail to his/her external email id or in the sap inbox, in R/3. with and without workflow activations. kindly suggest me, if there is any BADI or Functional Module to cater this requirement.
Regards,
Pankaj
