3 Steps to Creating Purchase Orders via API in Oracle R12

This tutorial explains the correct way to create purchase orders programmatically in Oracle Applications R12 using the Purchasing Documents Open Interface (PDOI). Instead of relying on unsupported private APIs, developers can insert data into PDOI interface tables and run the seeded Import Standard Purchase Orders program (POXPOPDOI). The article covers key tables, a sample PL/SQL script, error validation, and the benefits of PDOI—ensuring compliance, scalability, and long-term maintainability.
