How is the unique item identifier (UII) to be used in automated information systems?
In the Service or Agency material management and supporting automated information systems (AISs, developed or maintained in compliance with FMMP/FMEA requirements), once the UII is created from the separate data elements placed on the item, the UII shall not be parsed to determine the original elements, since parsing and recombination of the elements will invariably result in the introduction of errors in the UII. However, the UII, the enterprise identifier, the serial number and (in the case of Construct #2) the original part number will be captured separately at the time of inspection and acceptance. The UII shall be a primary pointer or key data element for traceability in all computational functions including inventory acceptance, item accountability, storage, issue, receipt, valuation, maintenance, and disposal.
