SAP Enterprise Architecture Designer: Visualizing and Governing SAP Landscapes

SAP Enterprise Architecture Designer is a collaborative modeling tool that enables enterprise architects to capture, analyze and present their organization’s IT landscape in a format that business and technology stakeholders can understand and act on. Now extended through SAP LeanIX, an enterprise architecture management platform acquired by SAP in 2023, the toolset has become central to S/4HANA transformation planning, Clean Core governance and AI readiness assessment. SAPinsider research shows that 55% of organizations have already deployed a version of SAP S/4HANA or SAP S/4HANA Cloud, making architecture visibility a prerequisite for managing change at scale. Explore the resources below.

What Is SAP Enterprise Architecture Designer?

SAP Enterprise Architecture Designer is a user-friendly, collaborative tool for creating and maintaining a complete landscape architecture that is easy to capture and understand visually. It supports business process models, enterprise architecture diagrams, process maps, requirements lists and data models, including reverse-engineered physical data models with generation to SAP HANA. Content can be consumed by browsing diagrams online, exporting them as SVG images, generating reports, running impact analyses and posting stakeholder comments. SAP LeanIX, now integrated within SAP’s business transformation suite, extends these capabilities with automated, data-driven enterprise architecture management across SAP and non-SAP landscapes at enterprise scale.

What Use Cases Are Referenced?

SAP LeanIX Governs Enterprise Architecture as the Rationalized Target State Hub

In SAP’s integrated transformation toolchain, SAP LeanIX governs enterprise architecture by mapping the IT landscape to define a rationalized target state while SAP Signavio handles process optimization and SAP Cloud ALM manages project execution. SAP has officially endorsed this suite to work in concert, providing a holistic framework for managing architecture, processes, data and quality across transformations.

FANUC Uses LeanIX to Visualize Landscape Impact Across Multi-Phase S/4HANA Migration

FANUC documented its existing heterogeneous IT landscape over several phases using SAP LeanIX, progressively visualizing steps toward an SAP-centric target state. The approach enabled FANUC to demonstrate the impact of new projects on landscape complexity, quantifying the number of applications and interfaces that would be removed, created or temporarily maintained during each wave of its S/4HANA transformation.

SoCal Edison Leverages LeanIX for Technology Rationalization During S/4HANA Rollout

Southern California Edison implemented SAP LeanIX as its enterprise architecture planning tool to monitor the impact of its S/4HANA transformation and assess whether it was achieving the intended transformative effects. The tool integrated technological capabilities, transformed processes and data, helping the utility make technology rationalization decisions by illuminating how capabilities aligned with specific processes and future-state architecture requirements.

Parle Deploys LeanIX Alongside Signavio and Cloud ALM to Anchor Clean Core Transformation

Parle Biscuits integrated SAP LeanIX, SAP Signavio and SAP Cloud ALM as its governance and lifecycle management layer during its multi-year transition to SAP Cloud ERP Private. The combination of architecture visualization, process optimization and project governance tools supported an approximately 30% reduction in total cost of ownership and two-times faster upgrade cycles by enforcing a clean core architecture across plants and markets.

UST Embeds LeanIX Into Governed SAP Delivery Models to Prevent Toolchain Complexity

Enterprise architecture tools like LeanIX only accelerate SAP delivery when embedded into governance rather than deployed as standalone components, according to UST. In their model, LeanIX operates alongside SAP Signavio, Tricentis, Syniti and SAP BTP within a coherent operating framework where artifacts flow consistently across tools, automation outputs are reviewed and changes are controlled as scope evolves — preventing tools from adding complexity rather than reducing risk.

SAPinsider ERP Migration and Transformation 2026

The SAPinsider ERP Migration and Transformation 2026 report surveyed 296 community members and found that 55% have already deployed a version of SAP S/4HANA or SAP S/4HANA Cloud. With 82% requiring integrations between core ERP and line-of-business applications as a top migration requirement, enterprise architecture tools that map application dependencies are essential for managing transformation scope and risk.

SAPinsider RISE with SAP 2025

The SAPinsider RISE with SAP 2025 benchmark report surveyed 122 community members and found that 17% of organizations are already using clean core setup and analysis tools and 38% are leveraging SAP BTP to externalize custom logic. Both trends reflect growing adoption of the architectural discipline that SAP Enterprise Architecture Designer and SAP LeanIX are designed to support and enforce.

SAPinsider SAP BTP Data, Integration and AppDev 2025

The SAPinsider SAP BTP Data, Integration and AppDev 2025 report found that organizations now integrate an average of 37 different applications with their SAP solutions — up from 33 in 2024. Managing this growing landscape complexity requires the kind of dependency mapping, impact analysis and architectural visualization that SAP Enterprise Architecture Designer and SAP LeanIX provide.
