In SAP S/4HANA Cloud Public Edition, setting up an integration scenario via the Fiori Communication Management apps requires two primary configuration objects. First, a Communication System must be created to represent the external system (the communication partner), defining its technical details like hostname and user credentials. Second, a Communication Arrangement is created. This object acts as a runtime instance that links a specific Communication Scenario (a predefined bundle of APIs) with the newly created Communication System, thereby activating the communication channel and generating the necessary technical user and service endpoints.

B. Communication API: You do not create the API itself during this process. The APIs are pre-delivered by SAP within a Communication Scenario, which you select when creating the Communication Arrangement.

D. Communication interface: This is a generic term. "Communication Arrangement" and "Communication System" are the specific, official names of the objects you must create in the SAP Fiori apps for this task.

"SAP S/4HANA Cloud - Communication Scenario": Documentation on the API Business Hub explains that a Communication Scenario is a design-time object that bundles the required inbound and outbound services (APIs). This confirms that the scenario and its APIs are used

not created

during the setup of a specific integration instance.
