SAP Architecture & Enterprise Integration
SAP ERP Certified consulting for S/4HANA landscape architecture, RISE with SAP migration, SAP BTP integration, and clean core programme delivery.
Understanding SAP Architecture & Enterprise Integration
SAP Architecture Consulting
Portamus provides SAP ERP Certified architecture consulting across the full SAP landscape — from S/4HANA migration strategy and system landscape design through to SAP BTP integration and clean core implementation. Our consultants bring certified expertise to complex SAP transformations in enterprise environments.
S/4HANA & RISE with SAP
RISE with SAP is SAP's business transformation offer combining S/4HANA Cloud, SAP BTP, and managed services into a single subscription. Portamus guides enterprises through the RISE migration journey — including landscape assessment, data migration strategy, custom code remediation, and cutover planning.
Clean Core & SAP BTP
SAP's clean core principle advocates keeping S/4HANA standard — avoiding modifications that impede upgrade cycles — and extending capabilities through SAP BTP (Business Technology Platform). Portamus designs BTP integration architectures and extension patterns that preserve clean core while delivering the custom functionality enterprises require.
Where Most Organisations Get Stuck
Complex S/4HANA Migration Scoping
Custom Code Modification Debt
Landscape Architecture Gaps
Integration Complexity Across Systems
Clean Core Compliance Challenges
Key Requirements
SAP transformation programmes require structured architecture decision-making across landscape design, migration strategy, integration patterns, and clean core governance.
SAP Landscape Architecture
Design the system landscape — including development, quality, and production tiers — optimised for S/4HANA deployment topology and operational requirements.
Migration Strategy
Select and plan the migration approach: greenfield (new implementation), brownfield (system conversion), or selective data transition — each with distinct architectural implications.
SAP BTP Integration
Architect integration patterns using SAP Integration Suite on BTP, connecting S/4HANA to third-party systems, legacy applications, and cloud services.
Clean Core Governance
Establish clean core principles and governance — identifying which customisations can be retained, which must move to BTP extensions, and which should be retired.
SAP Activate Methodology
Apply the SAP Activate implementation methodology across six phases: Discover, Prepare, Explore, Realise, Deploy, and Run — ensuring structured, governed delivery.
Scope of Engagement
Landscape Assessment
Evaluate the current SAP landscape, including system inventory, custom object analysis, integration mapping, and readiness for S/4HANA migration.
Migration Strategy & Roadmap
Define the migration approach (greenfield, brownfield, or selective data transition) with a phased delivery roadmap and architecture decision record.
Integration Architecture Design
Design the target integration architecture using SAP BTP Integration Suite, including API management, event mesh, and data pipeline patterns.
Clean Core Review
Analyse existing ABAP modifications, Z-objects, and custom code against clean core criteria, with recommendations for BTP extension or retirement.
SAP Activate Delivery
Structure programme delivery using SAP Activate, providing governance, phase gate reviews, and artefact management across all phases.
Architecture Governance
Establish SAP architecture governance — including Architecture Board participation, design authority, and standards for ongoing landscape management.
What You Walk Away With
SAP Landscape Assessment Report
Current-state analysis of the SAP landscape, including system inventory, custom code debt, integration complexity, and migration readiness scoring.

Target Architecture Blueprint
S/4HANA target landscape design including system topology, deployment model, and integration architecture.
BTP Integration Architecture
Design of SAP BTP integration patterns, API interfaces, event-driven flows, and third-party connectivity.
Clean Core Remediation Plan
Prioritised plan for remediating custom code and modifications to achieve and maintain clean core compliance.
SAP Activate Programme Plan
Structured delivery plan across SAP Activate phases with milestones, governance gates, and resource requirements.

How We Structure This Engagement
Understanding
Assess the SAP landscape through system discovery, custom code analysis, integration mapping, and stakeholder workshops.
Analysing
Define the migration strategy, identify clean core gaps, and design the target architecture blueprint.
Designing
Produce the S/4HANA landscape design and SAP BTP integration architecture with detailed architecture decision records.
Realising
Deliver the migration programme through SAP Activate phases — Explore, Realise, and Deploy — with governed architecture checkpoints.
Validating
Conduct architecture review and quality assurance at each Activate phase gate before cutover.
Running
Support post-go-live stabilisation and establish ongoing architecture governance for the SAP landscape.
