Mass update of Category Names on Purchasing documents

Hi,

Our City Procurement team is working on a project to simplify the current list of commodity codes and once finalized, would like to update the commodity codes on purchasing transactions i.e. Open Requisitions, Purchase Orders, Agreements and want to know the options available to do so in a single go instead of querying each record and updating manually.

FYI - we can update commodity code on Approved Requisitions by withdrawing and editing but the same is not possible to do on POs & AGTs. Please review this business need and provide us the solution to do using REST APIs/SOAP services.
