    Key Features

    • Multiple ERP Instances Support: Configure and manage multiple SAP Ariba ERP sources separately within S2P, each identified by a unique ERP source and connection alias.
    • Service Mappings: Predefined mappings enable data synchronization between S2P and SAP Ariba for entities such as legal entities, purchasing organizations, currencies, payment terms, GL accounts, cost centers, departments, suppliers, and invoices.
    • Customizable Integration Logic: Modify service element maps to tailor the integration behavior to specific ERP requirements.
    • Authentication Profiles: Use basic authentication profiles linked to SAP Ariba integration credentials for secure web service communication.

    Configuration Steps

    • Define the SAP Ariba ERP source in S2P.
    • Create and register a basic authentication profile using SAP Ariba integration user credentials.
    • Associate the authentication profile with service maps for relevant data entities.
    • Configure service maps and subflows to retrieve and update data on legal entities, currency rates, purchasing organizations, payment terms, GL accounts, cost centers, departments, suppliers, and invoices.

    Prerequisites

    • Assign the roles snfcmsintg.admin and snspendintg.admin to the integration user.
    • Obtain ERP integration user credentials and REST API details from your ERP team.
    • For multiple SAP Ariba instances, configure Source-to-Pay integration separately for each ERP source.

    Benefits for ServiceNow Customers

    By implementing this configuration, customers can automate and streamline procurement data flows between ServiceNow S2P and SAP Ariba ERP, improving data accuracy and operational efficiency. The ability to manage multiple SAP Ariba instances and customize integration logic ensures flexibility to meet complex organizational requirements.

    Configure your Source-to-Pay (S2P) instance to support inbound and outbound integration with your ERP system. This integration configuration enables you to post purchase order, receipt, invoice, and download primary data automatically from the ERP system.

    ERP source configuration enables the implementation of specific logic to populate values pertinent to third-party ERP systems. It includes all service mappings defined between Source-to-Pay (S2P) and the third-party ERP system. If multiple ERP sources exist, they’re stored as distinct ERP source entries with their corresponding service mappings.

    To meet specific requirements, you can customize the service-mapping logic by modifying the relevant service element map entry within the service map record. For organizations using multiple ERP systems, an ERP Source field has been incorporated into the tables to accurately identify the respective integrated ERP system.

    The ERP source configuration for SAP Ariba enables customers to establish multiple SAP Ariba instances. Each instance is identified by a distinct source, and the connection alias for each instance must be unique.

    Prerequisites

    Before you start the integration configuration, complete the following tasks.
    • Add the following roles to the Integration user:
      • sn_fcms_intg.admin
      • sn_spend_intg.admin
    • Get the following details from the ERP team:
      • ERP integration user credentials.
      • REST API details based on your ERP system you're using for the integration.
    Note:
    If the application must support multiple ERP instances, configure Source-to-Pay to integrate with each ERP instance separately.
