Definition:
Multi-ERP RAG (Retrieval-Augmented Generation across multiple Enterprise Resource Planning systems) is an AI architecture that allows a Large Language Model (LLM) to query and synthesize information from multiple disparate ERP systems in real-time to answer business questions accurately.
Think of it like having a super-smart assistant who can instantly look up information from your company’s SAP, Oracle, Microsoft Dynamics, and custom systems—all at once—and give you a unified, accurate answer.
