Modernize Without Migrating

You don't need S/4HANA to modernize your ERP. Extract more value from ECC through automation, cloud extensions, analytics, and UX improvements.

Overview

The Modernization Imperative

SAP ECC is a stable, proven platform. But it's showing its age in user experience, integration patterns, and operational efficiency. The good news: you can modernize the parts that matter most without ripping out the core.

Pro tip: Modernization investments aren't wasted if you later move to S/4. Fiori apps, BTP extensions, and cloud integrations are forward-compatible.

Strategy

Four Modernization Layers

Each layer can be tackled independently, allowing you to prioritize based on your biggest pain points.

1

User Experience

Modern interfaces without touching ECC

Replace clunky SAPGUI with modern, role-based interfaces. Users get consumer-grade UX.

SAP Fiori — ~200 apps available for ECC
Neptune/OpenUI5 — Custom Fiori-style apps
Low-code — Mendix, OutSystems, Power Apps

Quick win: Start with 3-5 high-volume transactions

2

Integration & Extension

Connect ECC to modern services

Connect ECC to cloud services, modern APIs, and third-party apps without middleware complexity.

SAP BTP — Cloud extensions for ECC
iPaaS — MuleSoft, Boomi, Workato
Event-driven — Real-time triggers to external systems

Quick win: Customer/supplier portal via BTP

3

Automation

Eliminate manual, repetitive tasks

RPA, workflow automation, and intelligent document processing to reduce manual effort.

RPA — UiPath, Blue Prism, Automation Anywhere
Workflow — Power Automate, Nintex
IDP — Invoice/document processing with OCR+ML

Quick win: Automate mass data uploads (MM01, XD01)

4

Analytics & Insights

Modern BI and predictive analytics

Extract ECC data to modern platforms for real-time dashboards and self-service BI.

Cloud DW — Snowflake, Databricks, BigQuery
BI Tools — Power BI, Tableau, Looker
ML — Demand forecasting, anomaly detection

Quick win: Power BI dashboards for executives

Typical Investment

  • UX modernization (10-20 apps)$200K-$500K
  • Automation/RPA (10-15 bots)$150K-$400K
  • Analytics platform$300K-$800K
  • API/integration layer$250K-$600K

Expected ROI

  • 20-40% less manual effort
  • 30-50% faster decisions
  • 50-70% user satisfaction
  • 60-80% faster integrations

Decision Guide

When to Modernize vs Migrate

Modernize if...

  • You're staying on ECC through 2030+
  • Core processes work well, UX is the issue
  • Budget/timeline for S/4 not available yet
  • Need quick wins to buy time
  • Want to "try before you buy" cloud

Migrate if...

  • 2027 deadline forcing your hand
  • Core data model is broken
  • Need new S/4 functionality
  • Technical debt is unsustainable
  • Want platform for next 10+ years
