When testing a connection to an on-premise system via the Cloud Connector from SAP Cloud Integration, the Location ID is a mandatory parameter. The Location ID serves as a unique identifier for a specific Cloud Connector instance connected to an SAP BTP subaccount. This allows the SAP BTP connectivity service to route the test request to the correct Cloud Connector, especially in scenarios where multiple Cloud Connectors are connected to the same subaccount for high availability or to access different on-premise landscapes. The "Test Connectivity" tool in the monitoring section explicitly requires this parameter for the 'On-Premise' proxy type.

A. Connector ID: "Connector ID" is not the correct terminology for the parameter used in the Cloud Integration connectivity test tool. The official parameter name to identify the Cloud Connector instance is "Location ID".

B. Host: While the virtual host and port of the backend system are also required for the test (entered in the 'Address' field), the Location ID is the specific parameter that identifies the Cloud Connector itself, which is the connection provider.

D. Subaccount ID: The test is performed within the context of a specific SAP BTP subaccount where the Cloud Integration tenant is running. Therefore, the Subaccount ID is implicitly known and not a parameter you need to provide manually.

Performing Connectivity Tests:

In the section describing the HTTP connectivity test

the documentation states

"For the On-Premise proxy type

you also need to specify the location ID. The location ID identifies the Cloud Connector that is used for the connection to the on-premise system." This directly confirms that the Location ID is a required parameter for this specific function.

Cloud Connector

Initial Configuration:

The documentation defines the Location ID: "An optional

unique ID that identifies the Cloud Connector. It is used for routing purposes within a subaccount. For example

if you have two Cloud Connectors connected to the same subaccount

you can distinguish them using different location IDs." This explains the fundamental purpose of the Location ID in the BTP landscape.
