  Order Management subsystem is a component of the WebSphere Commerce Server that provides shopping carts, order capture, order fulfillment, inventory, and payment function support. First let us go through concept of Requisition Lists in Websphere Commerce. Requisition Lists Requisition list is created for ordering items frequently .There can be two types of Requisition lists. 1. Private Requisition List  –This can be viewed and modified by the user who creates it. 2. Shared Requisition List -This can be viewed and used by users in the same organization. Requisition lists are stored in ORDERS table. In  ORDERS  table  STATUS  column is used to identify the requisition lists. A value of  Y  indicates that it is a  private requisition list . A value of  Z  indicates that it is a  sharable requisition list.  If you need to change the type of requisition list you must call the RequisitionListUpdateCmd. Users can add items from requisition list to order and requisition list remain unaltered
