Many SAP customers rely on the Customer Service module of SAP ECC, and service capabilities of SAP Customer Relationship Management, for their after-sales service processes. This is Part II of a two-part series, focusing on aspects of continuity from SAP ECC and SAP CRM. We will be looking at the new process variation that we call Maintenance Service. It is a service process that combines the best of SAP S/4HANA Service and Asset Management. This scenario is especially useful for industries where maintenance technicians maintain complex assets owned by their organization (maintenance management) and the same technicians also provide maintenance services for external parties and need to bill these services. The maintenance service order (MSO) and maintenance order (MO) are the core business transactions used in the maintenance service process. When a maintenance service item is released, a corresponding maintenance order is created. After service completion, the billing process is carried out through the Dynamic Item Processor (DIP).
