    Summary of Configure the Source-to-Pay integration with SAP

    This guide explains how to integrate ServiceNow's Source-to-Pay (S2P) application with SAP systems, including SAP ECC and SAP S4 HANA. The integration enables automated synchronization of procurement-related data such as purchase orders, receipts, invoices, and primary data between ServiceNow and SAP. Authentication between systems is established by creating a custom OAuth application within SAP.

    Key Features

    • Activation and Setup: Activate the Source-to-Pay integration and related SAP spokes (SAP ECC RFC, SAP S4 HANA Public Cloud, SAP S4 HANA OData) from the ServiceNow Store to enable integration capabilities.
    • Integration Framework: The Source-to-Pay integration framework handles pulling tasks and primary data from SAP into ServiceNow using configurable scheduled jobs.
    • Dependency Installation: Installing the Source-to-Pay integration plugins automatically installs required dependencies for Primary Data integration, Supplier Lifecycle Operations, Sourcing and Procurement, and Accounts Payable Operations with SAP.
    • ERP Source Configuration: Configure the ERP source within ServiceNow to define connection details, map integration payloads to SAP tables, and set up authentication credentials.
    • Integration Service Management: Create integration service records with SAP connection endpoints and authentication profiles. Separate service records can be customized per service request.
    • Data Synchronization: Schedule jobs to fetch primary data (e.g., currencies) from SAP ERP sources into ServiceNow automatically, or manually trigger inbound flows or subflows as needed.

    Practical Benefits for ServiceNow Customers

    • Achieve seamless, automated data exchange between ServiceNow Source-to-Pay and SAP ERP systems, reducing manual data entry and errors.
    • Leverage prebuilt integration spokes and frameworks to simplify setup and maintenance of SAP integrations.
    • Enable real-time visibility and management of procurement and supplier lifecycle operations within ServiceNow, powered by live SAP data.
    • Customize integration service endpoints and schedules to fit organizational workflows and data synchronization requirements.
    • Maintain security and control by using OAuth-based authentication and separate integration service configurations.

    Integrate the ServiceNow instance with SAP by creating a custom OAuth application in SAP ECC and SAP S4 HANA to authenticate ServiceNow requests.
