SAP ECC / S/4HANA RAP Techno functional Developer
Washington, DC
Full-time
Hybrid
Senior Level, Lead/Staff
15+ years expDice is the leading career destination for tech experts at every stage of their careers, and they are seeking a SAP ECC / S/4HANA RAP Techno functional Developer for their client, Mindlance. The role involves adapting custom ABAP code for S/4HANA, delivering scalable solutions, and ensuring compliance with SAP's architectural direction.
Computer Software
Responsibilities
Analyze and remediate legacy custom code to align with S/4HANA simplifications, strict ABAP standards, and clean core principles
Reengineer existing ABAP programs for performance optimization on HANA using CDS, AMDP, and SQL tuning
Design and develop RAP-based services for transactional applications with upgrade-safe, extensible architecture
Build and expose OData services (V2/V4) to support Fiori apps and external system integration
Document functional and technical specifications with clarity, precision, and traceability
Walk through designs and specifications with stakeholders, incorporating feedback and gaining buy-in
Design end-to-end technical solutions based on functional requirements and simplification impacts
Develop and execute unit tests to validate logic and ensure readiness for integration testing
Migrate and adapt custom logic to the new S/4HANA data model (e.g., ACDOCA, MATDOC, BP)
Replace legacy BDCs and screen logic with modern BAPIs and OData APIs
Participate in fit-gap workshops, advising on standard vs. extensible approaches
Implement extensibility using Key User, On-Stack, or Side-by-Side models, based on solution context
Ensure compliance with security standards, including DCL-based and RAP-based authorization
Maintain code lifecycle discipline using Git, ATC checks, clean ABAP, and peer reviews
Bridge business and technical teams, providing insight into how design choices affect process outcomes
Diagnose simplification impacts by tracing SUM, ATC, syntax, and data-model errors back to the exact custom object or dependency
Resolve inconsistencies between ECC logic and S/4HANA requirements by adapting code to new frameworks (CDS reads, MATDOC, ACDOCA, BP, etc.)
Analyze custom objects (reports, forms, interfaces, workflows, enhancements) to determine what to delete, redesign, or reimplement using S/4HANA standard features
Triangulate issues across ECC, S/4, and multiple conversion cycles by comparing runtime behavior and identifying differences introduced by simplification
Perform root-cause analysis on conversion failures (missing config, mapping errors, deprecated functions, unsupported objects, broken SELECTs)
Adapt legacy enhancements to modern extension models (RAP behaviors, CDS-based logic, BTP extensions)
Collaborate with functional teams to interpret functional impacts and turn them into technical remediation tasks
Rebuild logic broken by HANA constraints such as implicit sorting, non-deterministic behavior, and nested SELECT loops
Design S/4HANA-compliant data access strategies (CDS, virtual data models, released APIs) for performance and upgrade safety
Validate converted objects across all cycles, ensuring fixes hold and regressions don’t appear in later SUM runs
Plan and execute adaptation waves so changes remain traceable, testable, and aligned with clean-core strategy
Realign interfaces broken by data-model changes, deprecated IDOCs, or API shifts in S/4HANA
Provide fast, tactical problem-solving to unblock defects caused by conversion anomalies or data inconsistencies
