The Purchase-to-Pay (P2P) process is a fundamental business workflow that encompasses the entire procurement cycle—from requisitioning goods and services to making payments to suppliers. In SAP S/4HANA, the P2P process is streamlined and optimized through integrated modules, real-time data processing, and an intuitive user interface powered by SAP Fiori.
This article explores the key components, configuration, and benefits of the Purchase-to-Pay process in SAP S/4HANA, highlighting how it enables organizations to improve procurement efficiency, compliance, and supplier collaboration.
The Purchase-to-Pay cycle in SAP S/4HANA involves several steps:
- Purchase Requisition (PR): Internal users create requests for goods or services.
- Source Determination: The system identifies suitable suppliers using source lists, contracts, or quotations.
- Purchase Order (PO): Buyers create and issue purchase orders to suppliers.
- Goods Receipt (GR): Receipt of goods or services is recorded, updating inventory and accounting.
- Invoice Verification (IV): Supplier invoices are checked against POs and GRs for accuracy.
- Payment Processing: Approved invoices are processed for payment.
Each step is integrated with financial accounting and inventory management to ensure accurate tracking and control.
