When establishing a connection from the SAP Cloud Connector to an SAP Business Technology Platform (BTP) subaccount for SAP Ariba Cloud Integration Gateway (CIG), the administrator must define several key fields. The Region is mandatory as it specifies the geographical data center of the BTP subaccount. The Subaccount or Account ID is the unique technical name of the BTP subaccount being connected. The Location ID is a customer-defined unique identifier for that specific Cloud Connector instance. While technically optional in the tool, it is a mandatory best practice for CIG to uniquely identify the on-premise system endpoint, especially when multiple systems connect to the same subaccount.

A. SAP Logical SystemID: This is an identifier configured within the SAP ERP or S/4HANA system to represent a specific client; it is not a field in the Cloud Connector subaccount definition.

C. Proxy Host: This is an optional network setting required only if the Cloud Connector needs to connect to the internet through a proxy server. It is not a mandatory field for all setups.

Cloud Connector - Initial Configuration: In the "Add a Subaccount" section

the documentation outlines the required fields for the initial connection wizard. It explicitly lists Region and Subaccount as mandatory fields. It also describes the Location ID field

stating

"An optional identifier for the Cloud Connector that is used by the subaccount... We recommend that you specify a location ID that is unique per subaccount." For robust integration scenarios like CIG

this becomes a de facto requirement. (See section: Cloud Connector -> Configuration -> Initial Configuration -> Add a Subaccount).

2. SAP Ariba Cloud Integration Gateway Configuration Guide (for SAP S/4HANA): This official guide details the steps for setting up the Cloud Connector for CIG. In the section "Configuring the SAP BTP connectivity cloud connector

" it instructs the user to: "In the Add Subaccount dialog box

choose the Region from the drop-down list. Enter the Subaccount ID. ... Enter a location ID for the Cloud Connector. The location ID must be unique for a subaccount if you are using multiple Cloud Connectors." This confirms its mandatory nature in the context of a CIG implementation.
