S/4HANA Technical Code Assessment
Planning a move from SAP ECC to S/4HANA? TICS analyses your custom ABAP code base and gives you a clear picture of what needs to change — before you start the migration project.
Overview
With SAP ending mainstream maintenance for ECC in 2027, organisations need clarity on what their custom code estate means for their S/4HANA journey. TICS provides focused technical code assessment and remediation services — the critical first step that gives you the data you need to plan migration timelines, budgets, and resource requirements with confidence.
TICS reviews all custom ABAP programs, function modules, and classes against S/4HANA simplification items and deprecated API lists. Each custom object is classified by risk: High, Medium, or Low. The output is a structured Custom Code Readiness Report with effort estimates for remediation of each flagged item and an executive summary suitable for management decision-making. This is a technical assessment only — TICS does not execute the migration, but tells you exactly what it will take.
Beyond assessment, TICS performs hands-on ABAP Code Remediation for the objects that need fixing — rewriting flagged programs using S/4HANA-compatible APIs, replacing obsolete SELECT statements with HANA-optimised queries, migrating classic Dynpro logic to Fiori/RAP equivalents where needed, and unit testing all remediated objects. TICS works alongside your SAP system integrator: TICS handles the custom code, they handle the migration.

Technology Stack
Use Cases
Real-world scenarios where this service delivers impact
Custom Code Readiness Report for a Manufacturing Company
A mid-sized manufacturer running SAP ECC with over 2,000 custom ABAP objects needed to understand their custom code exposure before committing to an S/4HANA project. TICS conducted a comprehensive code assessment, classified every object by risk level, identified decommissioning candidates, and delivered a readiness report with effort estimates that enabled the company to budget and plan their migration with confidence.
ABAP Code Remediation for a Retail Enterprise
A retail company had custom objects flagged as incompatible with S/4HANA, blocking their migration timeline. TICS remediated the affected objects — rewriting deprecated API calls, replacing obsolete SELECT statements with HANA-optimised queries, and unit testing each remediated object — clearing the technical blockers so their system integrator could proceed with the migration on schedule.
S/4HANA Readiness Assessment for a Public Utilities Provider
A public utilities provider sought an independent technical assessment to build the business case for S/4HANA migration. TICS delivered a Custom Code Readiness Report covering risk classification, remediation effort estimates, and an executive summary suitable for management decision-making, providing the technical foundation the leadership team needed to approve their migration investment.
