This lesson introduces the service processing scenario and the master data objects. It explains which settings in the master data are important for this process.
Work Breakdown Structure – manual account assignment
The Work Breakdown Structure Element (WBS) as a part of the project structure plan (PS) serves as a cost object for service processing. In SAP S/4HANA Public Cloud Edition, it is not possible to use a sales order item as a cost object for services with the option to allocate actual activity quantity to it. It is necessary to use the WBS for a service process. The scenarios that represent customer project production processes is as follows:
In addition to creating a sales order, you can also create a project. This is useful if you require the typical capabilities of the project in the Cost Object Controlling scenario, such as budgeting, availability control, Project Cash Management, Easy Cost Planning, employee assignment, division of the business project into various subprojects that can represent various tasks, responsibility areas, and assignments such as profit center and company code. In this scenario, the project is the leading object. This means that the system does not control the sales order item as a cost object but assigns it to a WBS, defined a project with billing.
Sales Order
The customer order is created as a sales order. The sales order item requires the item type TAD for services, so that it can be invoiced directly without delivery. The previously created WBS is manually assigned to the sales order item. For the revenue posted with the invoice to be allocated to the assigned WBS, a corresponding requirement type must be automatically assigned to the sales order item. This automatic assignment of the requirement type is carried out via a parameter in the material master of the service product.

Cost Center and Activity Type
The service is provided by the employees of the service cost center. In practice, time recording for the service provided is done using a so-called cross application time sheet (CATS). The WBS is specified with the recorded actual times so that an automatic service allocation can be made from the service cost center to the WBS. In the service process presented in this learning, however, the cross-application time sheet is not used, but a direct service allocation is posted from the service cost center to the WBS. By specifying the service type and the number of actual hours, the actual costs are allocated, which can be evaluated in the cost center report and in the project report.
Material master of the service product
A service also requires a material master. On the one hand, certain parameters are used to control whether the customer order item is managed as a service item and can therefore be invoiced without delivery. On the other hand, a parameter is assigned in the material master that ensures that the required requirement type for project-specific individual production is assigned to the customer order item. Finally, the product with its material master is also required to determine the internal price and sales price of the service. The internal price should correspond to the hourly rate of the service type of the service cost center.
Profitability Segment
The evaluation of the results of the service projects takes place on the one hand around the project system. On the other hand, the evaluation in the overall context of the sales area is also necessary and therefore Margin Analysis is used. For this purpose, the WBS is settled to Margin Analysis. The settlement rule in the WBS determines the granularity of the reporting in Margin Analysis. For example, the actuals of the WBS could be settled to characteristics like product group and customer group. However, product and customer groups can also be derived from the material master and customer master when settling to Margin Analysis. The characteristics, take over from the WBS plus the derived characteristics define the profitability segment as the target of the settlement within Margin Analysis. Multi-dimensional and top-down reporting in Margin Analysis enables the analyzing of the entire sales area.
