I am customizing the email personalisation in class CL_CUAN_MKT_EXEC_EXECUTE_EMAIL (Superclass CL_CUAN_MKT_EXEC_EXECUTE_ACTN). I wonder if I can access the Business Partner IDs of the target group members within this class. I could only manage to find the member key in MT_TG_MEMBERS (length 16), but I need the Partner ID (length 10). In the email action the member key is stored in lt_pers_content (see screenshot). Any ideas?
