Migrating EDI Processes from SAP PO to SAP Integration Suite

Why Move from SAP PO to Integration Suite?

SAP Process Orchestration (SAP PO) has long served as the backbone of enterprise integration. However, with SAP’s cloud-first strategy and the evolution of SAP Integration Suite (IS) on the Business Technology Platform (BTP), many companies are planning or undergoing migration from PO to IS. 

One of the most complex parts of this migration is the Electronic Data Interchange (EDI) layer. EDI plays a central role in supply chain, logistics, and financial data exchange. That makes it critical to handle the transition without disrupting operations or compliance. 

This blog outlines the migration of EDI scenarios from SAP PO to SAP Integration Suite, with a focus on architecture, steps, challenges, and best practices. 

Analyzing the Existing EDI Landscape in SAP PO 

Before migrating, it's essential to understand the current landscape in SAP PO: 

Key EDI Components in SAP PO: 

• Communication Channels: AS2, SFTP, HTTP, File adapters, etc.
• Mapping Technologies: XSLT, Java UDF, Graphical Mapping
• Message Formats: EDIFACT, ANSI X12, Flat File, IDoc
• Trading Partner Profiles: AS2 identifiers, certificates, routing configurations
• B2B Add-ons: Seeburger adapters or custom-built B2B components

This analysis helps identify which tools, mappings, and partner profiles need to be migrated, redesigned, or replaced. 

EDI Architecture on SAP Integration Suite 

Key Components: 

• Cloud Integration (CI):

Acts as the core runtime engine for building iFlows and routing messages. 

• B2B Integration Cockpit:

Includes tools for: 

• EDI Mapping Guidelines (EDIFACT/X12 to IDoc)
• Envelope handling, acknowledgments (997, CONTRL)
• Trading partner configuration

• AS2 Adapter:

AS2 communication can be handled using either: 

• SAP's built-in AS2 adapter
• Third-party managed EDI providers (like Seeburger Cloud)

• Monitoring & Logging:

SAP IS includes EDI message monitoring, trace logs, and alert notifications for proactive issue resolution. 

SAP Integration Suite Migration Strategy: Step-by-Step 

Let’s walk through a typical scenario: 
EDIFACT ORDERS → SAP IDoc ORDERS05 

Step 1: Analyze Existing Flows 

• List all EDI message types and trading partners
• Identify mappings (XSLT, UDFs)
• Document protocols and channels used

 Step 2: Set Up SAP Integration Suite 

• Activate Cloud Integration and B2B Cockpit
• Install or configure AS2 Adapter
• Set up connections to SAP S/4HANA or ECC (IDoc or SOAP endpoints)

Step 3: Rebuild iFlows and Mappings 

• Rebuild mappings using available EDI Mapping Guidelines
• Apply splitter/envelope logic using B2B components
• Validate mapping accuracy with real sample data

 Step 4: AS2 Setup and Security 

• Import certificates (public/private, signed/unsigned MDN)
• Configure AS2 IDs, endpoints, encryption algorithms (SHA-256)
• Perform partner-specific connectivity tests

 Step 5: Testing and Validation 

• Test end-to-end data flow for each trading partner
• Validate mapping correctness, envelope structure, and acknowledgments
• Include negative test cases (e.g., incorrect syntax, invalid partners)

Step 6: Monitoring and Alerting 

• Enable EDI Message Monitoring in B2B Cockpit
• Set up alerts for failed or delayed messages
• Use retry mechanisms where necessary

Step 7: Cutover to Production 

• Execute a dual-run phase if needed (PO and IS in parallel)
• Coordinate cutover with each trading partner
• Decommission PO channels after successful transition
