What must you create when you build an integration scenario using the SAP Fiori Communication...

When you build an integration scenario using the SAP Fiori Communication Management apps in SAP S/4HANA Cloud Public Edition, you must create a communication system and a communication arrangement. A communication system represents the communication partner within a communication, such as the system that calls or provides services. A communication arrangement defines the settings for a specific communication scenario, such as the authentication method, the communication user, and the service URL. You can use the Communication Systems app and the Communication Arrangements app to create and manage these objects in the SAP Fiori launchpad. References = Setting up Communication Management - SAP Learning, Setting up SAP Best Practices Integrations - SAP Learning, Setting Up Integrations in SAP S/4HANA Cloud Public Edition
