The Add-On for SAP Ariba Cloud Integration Gateway allows you to send or receive documents from SAP Ariba solutions and SAP ERP or SAP S/4HANA (on-premise) systems. This Add-On has multiple nodes to enable you to perform the necessary configuration activities sequentially.
This Add-On typically contains nodes for configuring Global Settings, General Settings, and Application-Specific Settings.
Global Settings consist of the configuration activities you must complete irrespective of the integration of any SAP Ariba solutions – SAP Business Network Integration, SAP Ariba Strategic Sourcing Solution Integration, or SAP Ariba Procurement Integration.
General Settings are the configuration activities you must undertake to integrate a specific SAP Ariba solution, regardless of any transactions/documents you adopt.

Application-specific settings involve the configuration activities you must perform for that specific transaction/document.
When you download an Add-On from SAP Service Marketplace, a file with the ".SAR" extension is downloaded. SAP's Add-On Installation Tool (transaction code SAINT) allows users to install and/or upgrade the Add-On directly from their standard SAP system. You do not need to access or restart the operating system. Numerous import conditions are checked before installation to ensure that only an Add-On compatible with the available SAP system can be installed. Follow the Instruction Wizard to complete the process. The SAP BASIS Admin person/team carries out this activity.
