Appendix A: SES and ERS Integration

This provides details for integrating Evaluated Receipt Settlement (ERS) with the SES object configurations in SAP S/4HANA, which would be useful for clients and suppliers that utilize ERS invoicing, allowing for ERS-specific tax details to be sent to SAP Fieldglass prior to invoice creation.

For certain clients and their applicable suppliers, a specific invoice process known as Evaluated ERS may apply. ERS is a specific procedure utilized by SAP for settling goods receipts automatically. When a client utilizes ERS, they agree with the vendor that the latter will not submit an invoice in respect of a purchase order transaction. Instead, the system posts the invoice document automatically on the basis of the data in the purchase order and goods receipts. This eliminates invoice variances of settling goods receipts automatically.

With the ERS integration, specific vendors or suppliers that are classified as utilizing the ERS process will have specific tax codes, calculations, and details that are not currently supported on invoicing in the SAP Fieldglass application. This update to the integration process and configuration for lean services procurement will allow an invoice that is tied to a PO and ERS-specific supplier to be created with ERS-specific tax detail sent to SAP Fieldglass prior to their invoice creation.

This integration is a specific SES and invoicing workflow that may be implemented and supported by clients using SAP S/4HANA and suppliers that utilize ERS invoicing.

As a starting point you should first ensure this guide is executed to support the standard lean services procurement workflow and configuration for the integration of Purchase Requests, PO, SES, and Invoice objects.

The steps below apply specifically to the SES object configurations, to update and allow the ERS process to apply for a client whenever it may be applicable. Some of these steps are repetitive of steps described earlier in this guide, but they should be followed and confirmed.
