Abstract: A software system efficiently procures operating resources within an enterprise. A requisition record generating module generates a requisition record for a requisition. The requisition record indicates at least an operating resource that a requestor desires to purchase. The requisition record generating module generates the requisition record responsive to a combination of input by a requestor and operating resource information in an operating resource information database. An approval path determining module. responsive to the requisition record and to approval rules in an approval rules database, determines an approval path for the requisition record, among various ones of a plurality of possible approvers, required to approve the requisition record. An approval path handling module guides the requisition record along the determined approval path, and the approval path handling module generates a global approval indication in response to the requisition record successfully traversing the approval path.
