Abstract: A system and method is provided for analyzing and fulfilling file requests within an organization, the file requests including multiple data items. The system and method includes storing delivered data items in at least one computer memory and executing instructions using at least one computer processor to perform multiple steps. The file request may be received over a network from a system user and analyzed to identify data items corresponding to the delivered data items. The request may then be cleansed by creating a delta list removing the data items corresponding to the delivered data items. The cleansed request may be transmitted for fulfillment to a fulfillment source. When a file corresponding to the fulfilled request is received, a response file combining the file corresponding to the received request with the data items corresponding to the delivered data items is created.
