This Document is basically about triggering email notifications to all the email addresses that are maintained against a Contact Person.
The standard SRM system triggers notification only to the email addresses that is marked as standard.
Please follow the below steps if you are looking to achieve the same-
1.) Go to SPRO and locate "define actions for document output".
2.) Select the "processing types" for BBP_PD_BID. Look at the "Smart Form Mail" processing class / method.
3.) If it is the standard class CL_PD_BID_PROCESSING_BBP, create a Z class of your own, copying the standard class.
4.) Modify the method PROCESS_BBP_BID_MAI_BCS of your Z class. Locate the comment "Create and send email" and make changes to that section to add more email recipients of that contact person.
5.) Replace the standard class with your custom class in the customization.
