The PO Change History menu item in the Oracle Purchasing Navigator gives you even more, at-a-glance detail about all past revisions made to archived purchase orders. This menu item uses a Web browser to display the archived revisions. You can then compare the current purchase order with a previous revision or view all past changes to the purchase order. You can see what fields changed and what the fields were before and after the change. This menu item is also part of Oracle iSupplier Portal, if you have access to the Purchasing responsibility within iSupplier Portal.

You can navigate to this window by selecting Change History in the Tools menu of the Purchase Order Summary window. If your organization has implemented the standard Oracle Purchasing menu, you can navigate to this window from the Purchasing responsibility, choose Purchase Orders and then PO Change History.
