1.

Role Context:

A global discrete manufacturing organization is executing a multi-year SAP S/4HANA transformation of unprecedented technical complexity:

Dimension Scale

Total RICEFWs

600+ across 12 workstreams

Interfaces

150+ across 12+ target systems (ECC, MES, PLM, Quality Management, Supply Chain Planning, Data Lake, Project Portfolio Management, Logistics, Trade Compliance, Tax Engines, MDM)

Custom Fiori Applications:

60+ apps, 10+ user personas

Custom ABAP Development:

300+ enhancements, Z-tables, Z-transactions, ZRFCs

Integration Patterns

5 coexisting patterns (IDoc, synchronous RFC, polling RFC, CPI i Flows, file-based AL11) — often inconsistently applied within the same system-pair

Error Handling Frameworks:

7 distinct frameworks (AIF, IDoc/BD87, SM58/SLG1, CPI Monitoring, batch job logs, MES retry/email, custom ASRS monitor)

BTP Footprint

CPI i Flows, PLMSI 3.0/AIG, Work Zone (CMO dashboard), AEM (pathfinder in progress)

Co-Existence Architecture

Bi-directional S4↔ECC interim state with sync interfaces

The program has four specialized technical teams that this role must unify under a single architectural vision:

Team Lead ScopeABAP / RAP / Integration Config

Senior Lead

Backend development, RFC/ALE/IDoc, AL11, AIF, Clean Core remediation

Fiori / UI5 / Launchpad

Senior Lead

Frontend development, Spaces & Pages, UX governance, BTP Fiori deployment

BTP Integration Suite & AEM

Senior Lead

CPI i Flows, AEM event mesh, RFC→AEM migration, error handling unification

BTP Build Work Zone

Senior Lead

Dashboard consolidation, Integration Ops Center, self-service portals

This role is the single point of architectural authority across all four teams — ensuring that backend services, frontend experiences, integration middleware, and digital workplace sites are designed as a coherent, interoperable, Clean Core-compliant solution rather than four independent workstreams producing fragmented outputs.

2.

Key Responsibilities:

Solution Architecture & Technical Governance

• Own the end-to-end technical architecture spanning S/4HANA core, SAP ECC (co-existence), SAP BTP (Integration Suite, AEM, Work Zone, BAS), and all external target systems — ensuring every component fits into a unified, documented architecture blueprint

• Establish and enforce an Integration Pattern Catalogue — defining the single recommended pattern for each scenario type (master data sync, transactional replication, event-driven notification, file-based batch, real-time lookup) and eliminating the current inconsistency where the same system-pair uses three different patterns

• Chair the Custom Code Governance Board — evaluate every proposed custom ABAP development, Z-table, Z-transaction, and ZRFC against Clean Core principles; approve, reject, or redirect to BTP-based alternatives

• Own the Clean Core remediation roadmap — prioritize the migration of existing custom code toward released APIs, RAP Business Objects, and BTP side-by-side extensions with effort estimates, dependencies, and sequencing

• Define and enforce API design standards — naming conventions, versioning strategy, error response formats, pagination patterns, and authentication mechanisms for all OData V4 services, RAP APIs, and CPI-exposed endpoints

• Produce and maintain the Technical Architecture Document (TAD) — the single source of truth for all technical decisions, patterns, standards, and component interactions across the program

Cross-Team Orchestration & Delivery Management

• Manage the four specialized technical teams (ABAP/RAP, Fiori/UI5, Integration Suite/AEM, Work Zone) — aligning priorities, resolving cross-team dependencies, and ensuring consistent delivery quality

• Orchestrate the interface between backend and frontend — ensure CDS views and OData services built by the ABAP/RAP team are designed for optimal Fiori consumption; ensure Fiori apps built by the UI team correctly handle backend error patterns; ensure both teams follow the same data model and field naming conventions

• Orchestrate the interface between ABAP and Integration Suite — ensure RAP Business Events published by the ABAP team align with AEM topic design managed by the Integration team; ensure AIF namespaces configured by the ABAP team are consistent with CPI error federation managed by the Integration team

• Orchestrate the interface between all teams and Work Zone — ensure dashboards, monitoring views, and self-service portals built by the Work Zone team correctly consume data from ABAP (AIF, IDoc status), Integration Suite (CPI monitoring, AEM metrics), and Fiori (app catalogue, navigation targets)

• Run weekly technical architecture review — review all in-flight designs, resolve cross-team conflicts, and make binding architectural decisions

• Manage technical debt register — track all known architectural compromises, deferred Clean Core remediations, and pattern inconsistencies with planned resolution dates

Error Handling & Operations Architecture

• Design the unified error handling strategy — define the target-state architecture that consolidates 7 error handling frameworks into a coherent model with a single operational dashboard

• Define error classification taxonomy — standardized error categories applied consistently across all 150+ interfaces regardless of underlying technology

• Design the operational monitoring architecture — how AIF, BD87, CPI Monitoring, AEM Dashboard, SM37 job logs, and custom monitors feed into the Work Zone Integration Operations Center as a single pane of glass

Co-Existence Architecture Ownership

• Own the S4↔ECC co-existence architecture — multiple bi-directional interfaces, data consistency rules, reconciliation framework, and eventual decommissioning plan

• Design anti-loop mechanisms for bi-directional sync — origin markers, correlation ID tracking, and publisher-side suppression logic applied consistently across all bi-directional interfaces

• Define the data reconciliation framework — what gets reconciled how often, what tolerance thresholds, and how variances are escalated

• Plan the ECC decommissioning sequence — as subsequent rollouts move more plants to S4, define which co-existence interfaces can be retired, in what order, and what the prerequisites are

Cutover & Go-Live Technical Leadership

• Own the technical cutover runbook — the 130+ activity sequence spanning system lockdown, data migration, interface activation, smoke testing, and go-live validation

• Make Gate 2 and Gate 3 Go/No-Go recommendations — post-migration data validation and post-interface-activation smoke test decisions based on technical readiness

• Define the rollback plan — technical steps, duration estimates, and decision criteria for rollback at each gate

• Lead the technical war room during cutover weekend — coordinating all four technical teams, basis, security, and external system teams through the 72–96 hour cutover execution

Stakeholder Management & Communication

• Serve as the single technical point of contact for the Program Director, functional workstream leads, and external system teams (MES, PLM, Quality Management, Supply Chain Planning vendors)

• Translate complex technical architecture decisions into business-impact language for non-technical stakeholders — explaining why a pattern choice matters, what a Clean Core violation costs, and how error handling gaps create business risk

• Produce weekly technical status reports — interface health, defect trends, Clean Core compliance metrics, and risk register updates

• Represent the technical architecture in steering committee meetings — presenting Go/No-Go recommendations, escalating blockers, and defending architectural decisions
