Enabling LLMs to Navigate ERP Systems

Exploring the intersection of Large Language Models and Enterprise Resource Planning — how AI can understand and automate complex SAP workflows.


Enabling LLMs to Navigate ERP Systems


Enterprise Resource Planning systems like SAP S/4HANA contain decades of business logic, custom configurations, and complex data relationships. The question is no longer whether AI will transform ERP — but how.


The Challenge


Traditional ERP automation relies on rigid, rule-based logic. Business rules are hardcoded in ABAP, workflows follow predefined paths, and any deviation requires developer intervention. This creates a gap between the flexibility businesses need and what their systems can deliver.


Where LLMs Fit In


Large Language Models bring a fundamentally different approach to ERP interaction:


Natural Language Processing for Documents

  • Interpreting unstructured supplier quotes and invoices
  • Extracting relevant data from emails and correspondence
  • Automating document classification and routing

  • Intelligent Decision Support

  • Learning from procurement patterns and historical transactions
  • Suggesting optimal approval routes based on context
  • Identifying spend optimization opportunities

  • Agentic Workflows

  • Using SAP Joule Studio and Agent Builder for autonomous task execution
  • Orchestrating between multiple AI platforms for scalable inference
  • Building self-improving procurement pipelines

  • The Research Perspective


    My doctoral research at the University of Mannheim focuses on creating frameworks that allow LLMs to understand ERP data structures, navigate complex module interactions, and generate actionable insights — all while maintaining the compliance and auditability that enterprise systems require.


    Conclusion


    The future of ERP lies in hybrid systems that combine the structured reliability of traditional business logic with the adaptive intelligence of modern AI. The goal is not to replace SAP — but to make it smarter.
