When creating account master data objects in SAP Service Cloud V2, Role can be included to define the account's function (e.g., customer, prospect). Account team member is also included to assign employees responsible for managing the account. According to SAP documentation, "Account master data includes attributes such as Role and Account Team Members to support customer relationship management." Title (B) is typically associated with contacts, not accounts. Contract data (D) is managed separately and not part of account master data creation.
