Modeling A2A Interactions

Context

Using A2A interactions you model the message exchange between two process components with the help of asynchronous and synchronous operations. SAP accesses models like these using interface patterns.

Procedure

Decide which interface pattern best suits your use case. Choose from the following interface patterns:
- Asynchronous Interface Patterns:
- Synchronous Interface Patterns:
  - Query Business Object in A2A Communication
  - Read Business Object in A2A Communication
Use the interface pattern to set the names of the operations and service interfaces. Use spaces between the parts of the name to make the names more legible in the modeling.

Example

The standardized name of a service interface of the interface pattern request confirmation is Request <X> Cancellation. The space disappears if you later create the specified service interface for this modeled service interface. The specified service interface in the ES Repository would also be called Request<X>Cancellation.
