# ERP Source Configuration for Coupa

# ERP Source Configuration for Coupa {#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 from the ERP automatically.

ERP source configuration enables the implementation of a specific logic to populate values relevant to third-party ERP systems. The configuration includes all service mappings defined between Source-to-Pay (S2P)
and the third-party ERP system. In cases where multiple ERP sources exist, they're stored as distinct ERP source entries with their corresponding service mappings.

To meet specific requirements, you can modify the service-mapping logic by updating 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 ensure accurate identification of the respective integrated ERP system.

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

## Prerequisites {#erp-source-configuration-coupa__section_e51_s23_rfc}

Before you start the integration configuration, you must get the following details from the ERP team:

* ERP integration user credentials.
* SOAP or REST API details based on your ERP system and the type of web services you're using for the integration.
* Roles to be added for the Integration users.

## ERP Source Configuration {#erp-source-configuration-coupa__section_t1p_523_rfc}

To perform the ERP Source configuration for Coupa, perform the following steps:

1. Define the ERP source that you want to integrate with Coupa integration.
2. Create a basic authentication profile that can be used for web service integration with Coupa.
3. Register the Coupa integration username and password to create the authentication profile and associate it to service maps.
4. Define source configuration for ERP source. The ERP source configuration determines the ERP source to which your ERP system connects. For more information, see [Define an ERP source configuration for Coupa](https://servicenow-prod.fluidtopics.net/46dbjfsxGANp2p5vcEIBiA "Define an ERP source configuration that specifies the Coupa ERP source to which the ERP system connects. Map the integration payload with the Coupa tables.").

5. Configure service maps for the following entities:
   * Currencies: Set up subflows for the source configuration to lookup currencies from Coupa.
   * FX Currency Rates

     Set up subflows for the source configuration to lookup FX rates from Coupa.
   * Legal Entities
