NEW OR SUPERSEDING NSN—When an item is received under a new or superseding NSN as reflected in the receipt document, prepare a new stock record that shows the same management data (e.g., allowance and HL/LL/SL) as the superseded stock record card. Reference the superseded NSN in the lowest block of the REQUISITIONS OUTSTANDING column as shown in figure 12-21. Then close out the stock record for the superseded item by lining through the allowance quantity and the HL/LL/SL quantities of SIM items, Line through the requisition data in the REQUISITIONS OUTSTANDING column, and reference the superseding NSN and authority in the lowest block of the colum as shown in figure 12-22.
