L[aM (line item number). And, UN's as you know, apply to either 1 item and 1 FSN, or they can cover several makes and models, each with a separate FSN. So, on a report you record the UN the same way it's car- ried on your property book. That is, for a UN covering only 1 FSN, all the info is reported on 1 line. And, for a multiple-line LIN you use a line for the UN on the PB header page. (And, that line'll report your total authorized allowance for the item like the item's header page does.) Then you'll use a separate line to report the on-hand quantities for each separate make and model (FSN) you have under that UN. cmi
