ERP source configuration determines the ERP source to which your ERP system connects. Map the integration payload with the SAP tables.

## Before you begin

Role required: sn_fcms_intg.admin

## About this task

By default, the base system includes one ERP source named SAP, which refers to the parent connection for SAP. If there are multiple SAP instances, multiple ERP sources must be configured, and the child connections for these SAP
instances should be referenced.

Each ERP instance requires a unique ERP source configuration. Therefore, 10 ERP instances need 10 configurations.

## Procedure

1. Navigate to AllFinance -- ERP IntegrationERP Source Configuration.
2. In the ERP Configurations view, select one of the following ERP source configurations based on your requirement:  
   * SAP ECC ERP
   * SAP S4 HANA Cloud
   * SAP S4 HANA OData

   {#define-erp-source-sap__ul_hdw_qm3_mfc}

   This configuration is available as a part of the base system.
3. To edit the ERP source, select here.
4. Select the required ERP source for the SAP ECC or SAP S4 HANA using the search option.
5. To create a new ERP source, perform the following steps:
   1. Select New.
   2. On the form, fill the fields.  
      {#define-erp-source-sap__table_yv1_r3j_q2c__entry__2}

      | Field | Description |
      |-|-|
      | ERP Source | ERP source for which the integration is required. For example, SAP ECC or SAP S4 HANA. |
      | Short Description | Summary of the ERP source. |
      | Active | Option to activate the ERP source. |
      | Amount Precisions | Amount precision of the ERP source. For example, 2. |

      Figure 1. Define a new ERP source configuration for S4 HANA OData
   3. Select Submit.  
      A new ERP source is created. Verify that the connection alias is also unique for each ERP source.  
      Note:  
      SAP integration can have multiple ERP sources. The Staging table displays the ERP source column, which you can use to distinguish which ERP the data belongs to.

## What to do next

By default, the SAP base system provides 14 integration services. For other SAP instances, you must perform the following:

* To modify each integration service, you can open the integration service and select here to. You can define element level mapping between SAP table fields and payload elements.
* Map the users and corresponding ERP User IDs by accessing the ERP User Mappings related list.
