## Prerequisites
 - You've access to the S/4HANA Cloud, public edition backend system
 - You've required authorizations. For more information, see [SAP Gateway Administrator Role](https://help.sap.com/docs/ABAP_PLATFORM_NEW/68bf513362174d54b58cddec28794093/24f82651c294256ee10000000a445394.html?version=202210.002).
 - You've noted down the **System Alias** of your customer system landscape. System aliases must be assigned to a service group to define communication between the **SAP Gateway Foundation** hub system and the backend system.

### You will learn
  - How to publish a service group

><span style="color:red"> Remember: </span>
>
-	You can skip this step if you have already published a service group. Services assigned in the backend system to an existing and already published service group are automatically addressable by consumers.
>
- System aliases for OData V4 service groups must be manually created.
 The steps followed in this tutorial completely depend on your system landscape.
