SAP ECC to S/4HANA Custom Code Remediation — ABAP Migration Agent
ERPPlugs provides an SAP Custom Code Remediation Agent for S/4HANA migrations. The agent scans your entire ECC custom code repository, identifies ABAP programs affected by S/4HANA simplification items, and generates AI-powered remediation suggestions via Joule. It covers deprecated function module replacement, HANA-optimized SQL migration (replacing SELECT * and nested SELECTs with CDS views and AMDP), obsolete transaction and table replacements, and Clean Core compliance checks. Automated test case generation validates remediated code. Compatible with SAP ECC 6.0 EHP4 and above migrating to S/4HANA 2023, 2024, or 2025. Custom enterprise pricing.
Analyse and remediate SAP ECC custom ABAP code for S/4HANA compatibility using AI-powered code suggestions, simplification item checks, and automated test generation.
Reduction in manual code remediation effort
Simplification item coverage for target release
Full custom code repository scan time
Deprecated function modules missed
What this connector does
The largest single cost item in most SAP ECC to S/4HANA migrations is custom code remediation. Enterprises typically carry thousands of custom ABAP programs, many written over 15-20 years, that reference tables, function modules, and transaction codes deprecated or restructured in S/4HANA. Identifying every affected line of code, understanding the business logic, and rewriting it for S/4HANA compatibility is a project that can consume months of senior ABAP developer time.
The ERPPlugs SAP Custom Code Remediation Agent dramatically accelerates this process. It connects to your ECC system via RFC, scans every program in your custom code namespace against the S/4HANA simplification items database for your target release, and produces a detailed impact analysis with severity ratings and effort estimates per program. For each finding, the agent generates remediation suggestions using SAP Joule AI, covering deprecated function module replacements, HANA-optimized SQL rewrites (converting SELECT * and nested SELECTs to explicit field lists, JOINs, CDS views, or AMDP methods), and obsolete table substitutions.
Clean Core compliance is built into the analysis. Programs that modify standard SAP objects, use direct database manipulation, or bypass standard APIs are flagged for refactoring toward SAP's recommended extensibility model. Automated ABAP Unit test generation produces test cases for every remediated program, validating functional equivalence between the original ECC code and the S/4HANA-compatible version. The result is a migration that takes weeks instead of months, with confidence that remediated code works correctly on the target S/4HANA release.

Built for teams that need reliable automation
The SAP ECC <-> S/4HANAconnector fits into finance, ops, and revenue teams that have outgrown copy-paste — the ones whose month-end close should not depend on a spreadsheet, whose ledger accuracy should not depend on human vigilance, and whose sales velocity should not stall behind an accountant's inbox.
Below are the roles that get the fastest return the moment this connector goes live. If yours is on the list, the payback is typically visible in the first billing cycle.

Frequently Asked Questions
The ERPPlugs SAP Custom Code Remediation Agent scans every custom ABAP program, function module, report, and enhancement in your SAP ECC system against the S/4HANA simplification items database. It identifies code that references deprecated tables (like BSEG, KONV, VBRP), obsolete function modules, and HANA-incompatible SQL patterns. For each finding, it generates a remediation suggestion with AI-powered code rewrites via SAP Joule, estimates remediation effort, and produces automated test cases.
The agent integrates with SAP Joule to generate context-aware ABAP code suggestions for each remediation item. When a deprecated function module or incompatible SQL pattern is identified, Joule analyses the surrounding code context, understands the business logic, and proposes a remediated version using S/4HANA-compatible APIs, CDS views, or AMDP methods. Developers review and accept or modify each suggestion, significantly reducing manual rewriting effort.
The ERPPlugs SAP Custom Code Remediation Agent supports migrations targeting S/4HANA 2023, S/4HANA 2024, and S/4HANA 2025. The simplification items database is version-specific, so the agent applies the correct rule set for your target release. Source systems must be SAP ECC 6.0 with Enhancement Package 4 (EHP4) or higher. The agent also supports the SAP RISE migration path for customers moving to cloud-hosted S/4HANA.
The agent identifies SQL patterns that perform poorly or fail on HANA, including SELECT *, nested SELECT statements, client-dependent open SQL, and FOR ALL ENTRIES without prior empty-check. Each pattern is flagged with a severity level and a remediation path. SELECT * statements are rewritten to specify explicit field lists, nested SELECTs are refactored into JOINs or CDS views, and performance-critical queries are candidates for AMDP conversion to push processing to the HANA database layer.
Yes, the agent includes a Clean Core compliance module that scores each custom program against SAP's Clean Core framework. Programs that modify standard SAP objects, use direct database modifications (EXEC SQL), or bypass standard APIs are flagged for refactoring. The goal is to reduce the custom code footprint and align with SAP's recommended extensibility model using RAP (RESTful ABAP Programming) and side-by-side extensions on SAP BTP where appropriate.
For each remediated program, the agent generates ABAP Unit test cases that validate functional equivalence between the original ECC code and the remediated S/4HANA version. Test cases cover the primary execution paths, boundary conditions, and exception scenarios identified during code analysis. The generated tests can be imported directly into your S/4HANA development system and run as part of the standard ABAP Unit framework during the migration testing phase.
