This article is a step-by-step tutorial on creating requisitions in Oracle Apps R12 using the Purchasing Requisition Open Interface and APIs. It covers inserting requisition data into the PO_REQUISITIONS_INTERFACE_ALL table, running the Requisition Import (POXPOREL) concurrent program, and monitoring results.
