WF_DESTRUCTOR is executed from an ABAP class that supports the interface IF_SWF_IFS_WF_DESTRUCTOR. This method is executed as soon as the corresponding workflow work item is set to status completed or logically deleted.The method
EVENT_RAISED is executed from an ABAP class that supports the interface IF_SWF_IFS_WORKITEM_EXIT. This method is executed as soon as the relevant workflow work item performs a status change that is defined in the interface.
