# Prepare your integrations for SAP S/4HANA — before cutover, not during

Most SAP programs underestimate integration complexity. We inventory every connection, document the business rules, and build the coexistence architecture that keeps you on schedule.

## The Problem

### Why SAP cutovers stall at the integration layer

Integration gaps are the leading cause of SAP go-live delays. Most are avoidable — if you find them early enough.

#### Hidden Integration Dependencies

SAP cutover programs routinely underestimate the number of integrations touching the source system. Custom ABAP, flat file feeds, and legacy middleware connections surface late — when it's costly to fix them.

#### Business Rule Complexity

Critical business logic buried inside BizTalk orchestrations, ABAP function modules, or custom middleware rarely has documentation. Without a clear inventory, replicating it accurately in the target system is guesswork.

#### Coexistence Risk During Transition

Phased SAP rollouts create a coexistence period where old and new systems run in parallel. Integration layers must serve both simultaneously — without double-processing or data mismatches.

#### Downstream System Readiness

Systems connected to SAP — WMS, TMS, EDI platforms, reporting tools — may not be ready for changed message formats, APIs, or event patterns. Gaps are discovered at cutover, not before.

## What Aidant Does

### Our integration readiness approach

A structured five-step methodology built around SAP program timelines — from pre-project discovery through hypercare.

01

### Integration Inventory

We catalog every integration touching the SAP landscape — middleware flows, EDI connections, file feeds, APIs, and custom ABAP interfaces — before any migration activity begins.

02

### Dependency & Risk Analysis

Each integration is scored by business criticality, transaction volume, and technical complexity. You get a clear view of what can move early and what needs careful sequencing.

03

### Business Rule Documentation

We extract and document routing logic, transformation rules, and exception handling embedded in your current middleware — ensuring they survive the transition with full fidelity.

04

### Coexistence Architecture

We design the integration layer to support parallel operation during phased cutover, including message routing, duplicate suppression, and rollback procedures.

05

### Cutover Support

We provide on-call integration support during the cutover window and hypercare period — fast triage, rollback execution, and real-time monitoring of integration health.

## What we deliver

### Integration Landscape Assessment

Full discovery of all integrations connected to the SAP environment, including undocumented and custom-built connections.

### SAP BTP Connectivity Planning

Architecture guidance for SAP BTP Integration Suite adoption, including API Management and Event Mesh configuration.

### Middleware-to-SAP Mapping

Translation of existing BizTalk, MuleSoft, or custom middleware logic to SAP-compatible formats and protocols.

### Pre-Cutover Validation

End-to-end integration testing in the SAP sandbox and pre-production environments before any production activity.

### EDI & Trading Partner Readiness

Review and update trading partner configurations to align with S/4HANA message formats and updated IDoc structures.

### Post-Go-Live Monitoring

Continuous monitoring of integration flows in the weeks following cutover, with rapid response to any processing exceptions.

## What a readiness engagement delivers

Organizations that complete an integration readiness assessment before SAP cutover consistently report fewer integration-related delays and higher confidence in their go-live date.

- Integration dependencies identified before cutover — not during
- Business rules documented and validated in the target system
- Coexistence architecture designed and tested in advance
- Reduced integration-related cutover delays and rollbacks
- Trading partners and downstream systems notified and ready
- Clear runbook for cutover and post-go-live support

## Client Example

### SAP and BizTalk integration readiness at global scale

Non-Profit / SoftwareSAP Integration with BizTalk Server

The largest software company serving non-profit organizations — 5,000+ associates, 40,000 customers across 60+ countries — needed SAP connected to external partners and customers via web services. A previous BizTalk implementation had been left incomplete, leaving critical integration points unresolved ahead of a broader SAP rollout.

Aidant redesigned the solution using Content-Based Routing and a canonical mapping pattern, enabling the client to handle new web service requests from trading partners without new BizTalk deployments. Document tracking, error handling, and a visibility dashboard were delivered as part of the engagement.

## Don't let integration gaps delay your SAP go-live

An integration readiness assessment typically takes 2–4 weeks and delivers a clear, prioritized action plan before your program schedule is at risk.
