necessary to maintain the prescribed average endurance level. Replenishment of SIM items are determined when expenditure transactions have been posted to the stock records. SIM items are replenished when the on-hand plus the on-order quantity is equal to or less than the low limit. Non-SIM items are replenished on a one-for-one replacement basis, depending on the availability of funds. Replenishment of AVDLR is accomplished on a one-for-one basis after a BCM action on the unservice- able turn-in. Automated activities can process stock replenish- ment by using the automatic reorder function in the computer system. This function can screen the stock records and prepare MILSTRIP requisitions for each deficient item. Receipts Receiving and storage personnel submit completed receipt documents to stock control. Stock control is responsible for checking the receipt documents for annotations and markings made by receiving or storage personnel. The annotations made in the receipt document determines the action required before processing the receipt through the computer program. Stock control personnel also must review receipt documents for completeness of information. This information includes the receipt signature, receipt date, quantity circled, and suffix code (record position 44). When processing receipts, compare receipt docu- ment data with stock control data. The following are some of the data that you should check: Cognizance symbol Stock number Unit of issue Unit price Quantity requisitioned Storage location After comparing the data, receipts that are in agreement can be processed by using local procedures. In receipts, the stock number is the most common data that is substituted from the original requisition. Before posting these receipts, check the requisition file for the supply status that contains information about the substitute stock number. You can distinguish a new or substitute stock number by status codes BG or BH, respectively. If status data is not listed in the requisition file, use other publications in the technical library to ensure the substitute data is correct. In automated activities, after posting the receipt, cross-reference records for substitute stock numbers are created automatically by the computer. A suffix code in record position (rp) 44 of a MILSTRIP format identifies partial receipts. When posting partial receipts, be sure to include the suffix code in the input. The term receipt not from due means that the document number of the material received is not in the outstanding requisition file. This situation exists when requisitions processed off-line are not recorded in the requisition file, but remain outstanding in the supply system. Other causes of unrecorded requisitions maybe push items from the ICP to ship’s stock for which there is no basic NSN file in the record. For whatever reason, the material arrives and stock control must process the receipt. Issues Stock control gets a copy of the proof of issue documents after the delivery of material to the customer. These documents have been edited by the aviation stores division (ASD) or supply support center (SSC) during the initial submission of requisitions. Upon receipt of the proof of issue documents, stock control posts the transactions in the stock records. In automated activities, the computer procedures allow automatic processing of issue transactions in the stock records. Transactions processed by ASD/SSC via NALCOMIS interfaces with and automatically posts into SUADPS tiles. For repairable items, automated activities post issue transactions for aviation depot-level repairable (AVDLR) items only after a BCM action by the IMA. Transfers Activities may transfer material only upon receipt of an authorized request from another ship or activity. A requisition is the most common form of request for transfer of material. Higher commands may direct transfer of material by message, letter, or memorandum. Stock control is responsible for processing material transfer by using the applicable procedures. After completing the transfer, shipping section personnel 10-4
