Procure-to-Pay (P2P) process map for FMCG tobacco manufacturers, spanning demand identification through invoice reconciliation with regulatory compliance checkpoints. The workflow connects eight core entities—Demand Identification, Purchase Requisition, Approval, Supplier Selection, Purchase Order, Goods Receipt, Invoice Receipt, and 3-Way Matching—each with detailed line-item and validation tables. Budget checks, quality inspections (including tobacco-grade and nicotine-content verification), and excise-duty tracking are embedded throughout to ensure compliance with tobacco industry regulations. This ER diagram enables procurement teams to design robust ERP schemas, audit trails, and control frameworks that balance cost efficiency with regulatory rigor. Fork and customize this diagram to map your organization's specific approval hierarchies, supplier evaluation criteria, and tax/duty handling requirements.
