Thanks Diane. From what I have read, in order to maintain customer data in CRM, the user has to have security access to Customer Maintenance in MAS as well. With than in mind, I thought hiding the menu option in MAS for a certain role might be a good alternative for keeping the needed security access but limiting the ability to maintain the data in MAS. I have found the global menu maintenance utility, sy_menu_ui, but have not found a way to maintain the menu by role.
