1. Executive Summary
In today’s enterprise landscape, organisations rely heavily on SAP for managing critical business processesfro, m finance and procurement to supply chain and human resources. Yet, while SAP provides a robust transactional backbone, it often lacks the agility and predictive intelligence that modern businesses demand. Recognising this gap, Presear Softwares, a leader in applied artificial intelligence and enterprise systems engineering, developed an advanced AI Integration Layer designed to enhance SAP ecosystems with machine learning, large language models (LLMs), and intelligent process automation.
The solution seamlessly connects with SAP modules such as S/4HANA, SAP BTP (Business Technology Platform), SAP Ariba, and SAP SuccessFactors, enabling data-driven insights, automated workflows, and contextual decision-making. This integration empowers enterprises to move beyond reactive operations and toward a proactive, intelligent enterprise model, one that learns, predicts, and adapts dynamically.
Through its AI Layer for SAP, Presear Softwares delivers measurable outcomes: 35–50% improvement in process efficiency, 45% reduction in manual interventions, and an enhanced decision latency of up to 60%. The framework combines deep technical integration, data governance, model transparency, and security compliance to ensure that AI augments, rather than disrupts, existing SAP environments.
2. Background
SAP systems have long served as the digital backbone of global enterprises. They manage complex operations, enforce business logic, and maintain transactional consistency across finance, logistics, procurement, and human resources. However, despite their extensive functionality, traditional SAP deployments often operate as static systems of record rather than adaptive systems of intelligence.
Most enterprise decisions based on SAP data still depend on human interpretation of reports and dashboards. Patterns in historical procurement, supply chain delays, or HR attrition may exist, but without a cognitive layer, enterprises struggle to extract real-time insights or predict anomalies before they occur. Manual workflows, legacy data models, and siloed modules further constrain SAP’s potential as a dynamic decision engine.
Presear Softwares identified this limitation as both a technological challenge and a strategic opportunity. As enterprises began adopting AI-driven frameworks in customer service and analytics, SAP environments remained comparatively underutilized. The need was clear: a non-disruptive, modular AI layer capable of integrating with existing SAP infrastructure, enhancing intelligence without overhauling the system.
Leveraging its expertise in artificial intelligence, data engineering, and enterprise automation, Presear Softwares conceptualized the SAP + AI Layer Integration Framework, an architecture designed to bridge structured ERP data with intelligent reasoning, pattern recognition, and natural language understanding.
3. Objectives
The SAP + AI Layer project was initiated by Presear Softwares with a clear set of objectives to align enterprise data management with predictive and generative intelligence:
Enhance Decision-Making: Enable AI-assisted recommendations and anomaly detection across SAP modules, allowing real-time decision support.
Automate Repetitive Tasks: Deploy machine learning models to automate document validation, invoice reconciliation, and procurement analysis.
Create a Conversational SAP Layer: Integrate LLMs to make SAP data conversational, allowing managers to “ask” for insights in natural language.
Maintain System Integrity: Ensure full compatibility with SAP BTP standards, role-based security, and audit compliance.
Enable Scalable Intelligence: Design the AI layer as a scalable microservice ecosystem, capable of supporting thousands of SAP transactions per hour.
4. Technical Architecture
4.1 Architectural Overview
The Presear AI Layer Architecture for SAP is built on a multi-tiered framework that integrates seamlessly with SAP’s data, application, and user interface layers. It enables data extraction, model inference, and reintegration, ensuring insights are presented contextually within SAP dashboards.
4.2 Layered Architecture

4.3 Data Flow (Illustrative)
SAP S/4HANA exports transactional or master data via OData REST API.
Data flows through SAP BTP Integration Suite, which securely connects to Presear’s AI microservice endpoints.
The AI Layer performs:
Predictive analytics (e.g., supplier delivery delay forecasting)
NLP summarization (e.g., executive summaries of monthly sales)
Document extraction (e.g., auto-processing of POs and GRNs)
The AI output is returned to SAP’s Fiori UI or Analytics Cloud, appearing as new fields, alerts, or visualization layers.
Event Mesh ensures bi-directional sync, AI-generated recommendations update relevant SAP tables or trigger SAP workflows.
