When establishing an integration scenario in SAP S/4HANA Cloud, Public Edition, using the Communication Management Fiori apps, an administrator must perform two key configuration steps. First, a Communication System is created to define the technical details of the remote system (the communication partner), including its hostname and authentication method. Second, a Communication Arrangement is created. This object links a specific Communication Scenario (which defines the APIs to be used) with the newly created Communication System, thereby activating the communication and generating the unique service endpoints for that integration.

B. Communication interface: This is a component of a communication scenario, which is typically pre-delivered by SAP and selected, not created, during standard configuration.

C. Communication API: Similar to an interface, an API is a service within a communication scenario. You configure its use via the arrangement, but you don't create the API itself.
