Service Interface

Service interfaces are named groups of operations. A service interface belongs to exactly one process component, whereas a process component can contain multiple service interfaces. Service interfaces specify offered (inbound service interfaces) or used (outbound service interfaces) functions.

The operations and service interfaces are modeled using predefined patterns to ensure that the naming and definition of services are unified. These interface patterns are derived from the access type needed and cover the majority of use cases. Thus, service interfaces, operations, and message types are always modeled in the same way. Interface patterns define naming rules for operations and service interfaces based on the business object and its node structure, grouping rules for the operations in the service interfaces, naming rules for the message types, and rules for the message choreography of an enterprise service interaction.

For example, the service interface Manage Sales Order In could provide the service operations Create Sales Order , Read Sales Order , Update Sales Order , and Cancel Sales Order .
