Service component interfaces (SCA) are always defined in the synchronous form. For each synchronous interface, one or more asynchronous interfaces can be generated.

When a service component is invoked synchronously, both the client (consumer) and the service provider execute in the same thread. The calling component within IBM® Business Automation Workflow is blocked until a response is received from the provider. Synchronous invocation can be selected on both request-response and one way operations.
