The report "Send SAP Information to Managed Gateway for Spend&Network" (transaction ARBCIGMASTERDATA) is a crucial initial setup step. Its purpose is to transmit fundamental system metadata from the on-premise SAP ERP or S/4HANA system to the SAP Ariba Cloud Integration Gateway (CIG). This data allows CIG to identify the connecting system and understand its software capabilities. The two key values sent are the SAP Logical System ID, which uniquely identifies the specific SAP client, and the software component details of the installed CIG Add-On, which is essential for version compatibility and applying correct integration logic.

B. Managed Gateway User ID: This report transmits system metadata, not user credentials. Authentication is managed separately through technical users and security certificates, not by sending user IDs in this payload.

D. SAP Application Server Hostname: The integration uses the SAP Logical System ID as the unique business system identifier, not the physical or virtual hostname of an application server.

It explicitly states that the report sends the SAP System ID (Logical System) and the Software Component Version to CIG.
