A Scalable Control Architecture for Centralized Procurement Approval in Distributed ERP Landscapes

Abstract

Large enterprises often operate multiple business units within a shared Enterprise Resource Planning (ERP) system to support regional and operational needs. While this structure enables local procurement efficiency, it can limit centralized oversight for asset-based and high-value purchases [1]. In many ERP environments, approval workflows are configured at the operating unit level, making it difficult to enforce consistent enterprise-wide approval policies without restructuring organizational entities [2]. This paper presents a scalable control approach that enables centralized approval for selected procurement transactions while allowing routine purchases to continue through existing local approval paths. The method uses item classification and configurable monetary thresholds to identify transactions that require additional oversight. When predefined conditions are met, approval is automatically routed through enhanced review steps within the existing ERP workflow framework [2][3]. By embedding conditional approval logic into standard procurement processes, the approach strengthens financial oversight without disrupting day-to-day purchasing operations. The method provides a practical balance between decentralized execution and centralized governance, supporting procurement risk management objectives in distributed ERP environments [4]. The proposed framework offers a reusable and adaptable solution for enterprises seeking improved approval consistency and audit readiness.
