# ERP source configuration for SAP Ariba

# ERP source configuration for SAP Ariba {#ariaid-title1}

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 {#erp-source-configuration-sap-ariba__section_cvl_z5t_p2c}

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
  {#erp-source-configuration-sap-ariba__ul_n2b_cvt_p2c}
* 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.

## ERP Source Configuration {#erp-source-configuration-sap-ariba__section_ucl_kvt_p2c}

To configure the ERP Source for SAP Ariba, perform the following steps:

1. Define the ERP source that you want to integrate with the SAP Ariba integration.
2. Create a basic authentication profile that can be used for the web service integration with SAP Ariba
3. Register the SAP Ariba integration username and password to create the authentication profile and associate it to service maps.
4. Define the source configuration for ERP source. The ERP source configuration determines the ERP source to which your ERP system connects. For more information, see [Define ERP source configuration for SAP Ariba](https://servicenow-prod.fluidtopics.net/qmem_rm8S3TaDu5u9fI9dQ "ERP source configuration determines the ERP source to which your ERP system connects. Map the integration payload with the SAP Ariba tables.").
5. Configure service maps for the following entities:
   * Legal Entities

     Set up subflows for the source configuration to lookup legal entities or company code details from SAP Ariba.
   * FX Currency Rates

     Set up subflows for the source configuration to lookup FX rates from SAP Ariba.
   * Purchasing Orgs

     Set up subflows for the source configuration to lookup purchasing organizations from SAP Ariba.
   * Currencies
