⚠️ SAP ECC END OF MAINSTREAM MAINTENANCE
2027
Your Custom ABAP Code
Won't Survive the Transition
SAP ECC maintenance ends in 2027. Every line of custom ABAP code, every Z-program, every enhancement — needs to be analyzed, converted, or retired.
The Technology Gap
Your ECC customizations were built for a different era
ECC Legacy Stack
Dynpro Screens
ALV Grid Reports
Web Dynpro ABAP
BSP Applications
RFC Function Modules
BOPF Business Objects
Gateway SEGW (OData V2)
S/4HANA Stack
Fiori / SAPUI5
Fiori Elements
Fiori Elements
SAPUI5 Freestyle
RAP Services
RAP Business Objects
CDS + OData V4
What Breaks in S/4HANA?
SAP's simplification changes everything
🗄️
Table Changes
BSEG, KONV, VBFA and 300+ tables restructured or removed entirely
⚙️
Deprecated APIs
Thousands of function modules marked obsolete with no direct replacement
🖥️
UI Technology
Dynpro, Web Dynpro, BSP — all incompatible with Fiori Launchpad
🔗
Data Model
HANA-optimized tables require CDS views, not classic ABAP SELECT
🔌
Integration
OData V2 services need migration to RAP-based OData V4
📋
Business Logic
BAdIs, enhancements, and exits need Clean Core compliance
14 Categories of Objects Need Conversion
Every custom development must be analyzed and transformed

Why Act Now?
The cost of waiting only increases
⏰
Aging Technology
Dynpro was designed in the 1980s. Your business deserves modern, responsive interfaces.
🐌
Inefficiency
Legacy code can't leverage HANA's in-memory capabilities. You're leaving performance on the table.
👨💻
Talent Scarcity
Developers who know Dynpro and classic ABAP are retiring. New talent learns Fiori and RAP.
🔮
Future-Proofing
SAP's roadmap is clear: Clean Core, RAP, and Fiori. Everything else is technical debt.
The Pain of Manual Conversion
What teams face doing this the traditional way
- Analysis Paralysis: Weeks spent just cataloging what exists
- Knowledge Gap: Few developers know both legacy AND modern patterns
- Repetitive Work: Same conversion patterns applied hundreds of times
- Error Prone: Manual rewriting introduces new bugs
- No Consistency: Different developers, different approaches
- Testing Nightmare: Each conversion needs full regression testing
- Documentation Debt: Who has time to document during crunch?
How will your team convert
thousands of objects
in 24 months?
With the same resources. The same budget. The same timeline.
The S/4HANA Migration Challenge
Demands a Smarter Approach
Manual conversion is expensive, slow, and risky.
There has to be a better way.
