Call BADI on click of button
I am implementing BADI BBP_CUF_BADI (in SRM 4.0) to display a customized screen. My queries are
1) How do I call the BADI BBP_CUF_BADI when the buyer clicks on the approve/order button in the SRM portal.
2) After implementing the BADI what are the steps that I need to carry out to display the customized screen in the SRM portal?
Thanks and Regards,
