WAWF and UID Registry

WAWF (Wide Area Workflow and IUID Registry)
Wide Area Work Flow (WAWF) is a means of transmitting Item Unique Identification (IUID) data elements into the IUID Registry. The WAWF is a transaction system, supporting a distinct part of the procurement lifecycle from submission of electronic invoices through inspection and acceptance to electronic payment receipt. The IUID Registry is the ultimate repository where all IUID data will be captured.

The IUID Registry is populated as new items are acquired, or as legacy items are assigned IUIDs. The IUID Registry is maintained by the Defense Logistics Information Service (DLIS).

Wide Area Workflow (WAWF) Description
Wide Area Workflow (WAWF) is a secure web-based system for electronic invoicing, receipt and acceptance. WAWF creates a virtual folder to combine the three documents required to pay a vendor – the contract, the invoice and the Receiving Report. The WAWF application enables electronic form submission of invoices, government inspection, and acceptance documents in order to support DoD’s goal of moving to a paperless acquisition process. It provides the technology for Government contractors and authorized DoD personnel to generate, capture, and process receipt and payment-related documentation, via interactive Web-based applications. Authorized DoD users are notified of pending actions by e-mail and are presented with a collection of documents required to process the contracting or financial action.

Benefits of the WAWF include online access and full spectrum view of document status, minimized re-keying and improving data accuracy, eliminating unmatched disbursements and making all documentation required for payment easily accessible. WAWF is the system that allows DoD to reach its e-invoicing goals and reduce interest penalties due to lost or misplaced documents.

IUID Registry Data Elements
The submission of IUIDs to the IUID Registry requires several pieces of data for each marked item in addition to contract and shipment numbers, the item number (CLIN), product identifier (NSN/PN) and unit cost:

  • UID Type (Construct 1 or 2)
  • Entity Identifier (such as CAGE) of company assigning the UID
  • IAC (Issuing Agency Code) which controls the Entity ID
  • Part Number (Construct 2 only)
  • Serial Number
  • Fully constructed UID
