Nine Interfaces Built to Move Procurement from SAP to Coupa

Company Overview

A manufacturing organization with offices across the United States and Canada, running SAP ECC across supply chain, finance and controlling, plant maintenance, enterprise asset management, procurement, human resources, and business intelligence. The objective was to decommission the existing procurement platform and move the integration from SAP to Coupa.

Before: A Procurement Platform Due for Replacement

• Procurement ran on a platform the organization had decided to retire, with the integration to SAP built around it.
• Day-to-day transactions between vendors and the business carried avoidable cost.
• Vendor communication and clearing were slower than the business needed.
• The change sat inside a much larger supply chain program, so the integration work had to land without disrupting everything around it.

The Solution

Nine new interfaces were designed and configured spanning both directions between SAP and Coupa, covering chart of accounts, inbound and outbound purchase orders, inbound and outbound goods receipts, invoice approval, vendor master, users, and payment confirmations. New document types were configured with their own number ranges, commodity code reporting was designed and mapped to material groups, and a complete error handling and resolution system was built for day-to-day invoice processing. Delivery ran with a team of 15 to 20 people as part of the wider supply chain and procurement program.

After: Automated Procurement on a Single Integrated Platform

• Nine interfaces delivered covering the full procurement cycle in both directions between SAP and Coupa.
• Faster vendor communication and clearing, shortening the cycle from transaction to payment.
• Procurement automation across purchase orders, goods receipts, and invoicing.
• Vendor classification and performance indicators established for ongoing supplier management.
• Error handling built in rather than bolted on, giving the team a defined path to resolve day-to-day invoice exceptions.

Efficiency Gains

• Significant cost reduction on day-to-day transactions between the business and its vendors.
• Commodity code reporting mapped to material groups, enabling spend visibility that was not previously available.
• A smoother and more connected supply chain across the wider program.
• Successful platform transition with the integration moved fully onto Coupa.
