prepares and submits financial reports and maintains various files. This includes the manual and mechanized output files. Stock control personnel encode input documents and check codes inserted by other personnel in the supply department. Stock control also prepares requests for reports and listings and interprets computer output data. It is clear that the accuracy and completeness of the computer product will be no better than the accuracy and completeness of the stock control personnel’s efforts. FUNCTIONS Stock control personnel act to facilitate paperwork flow while accommodating computer requirements within SUADPS constraints to perform the supply functions described in the following paragraphs. Files Stock control maintains mechanized and manual files. Refer to the SUADPS-RT Support Procedures for lists of mechanized files. The following paragraphs describe some of the manual files maintained by stock control. The Stock Control History File contains a copy of transaction documents, such as issues, offship requisitions, change notices, and receipts. The material completed file contains the copy of completed procurement documents submitted by ship departments. The receipt file contains a copy of all signed shipping documents used to process the receipt transaction. The data processing history file consists of all computer-generated listings or documents used for updating the records. Stock control also maintains copies of reports generated by the computer system. Stock control uses these reports when conducting an audit trail for a specific item or document number. Updates An update is the processing of collected transactions or information into the computer system. The process includes inputting information to the system tape files, which allows the system to produce a report or printout. Stock control manages the update by specifying what input documents should be processed first. Stock control does this by submitting a request for update to the systems coordinator, together with requests for specific reports and other output. Computer systems with real-time capability update records automatically when customers enter transactions in the computer. Stock records are normally updated monthly based on change notice management information provided by SPCC. A complete reconciliation of stock record data should be accomplished with SPCC once a year. Each fiscal year, a unit price change tape will be received from SPCC to update the unit price information in the stock records. The unit price change tape normally has an effective date of 1 October. Procurements Stock control is responsible for buying material for the ship and embarked squadrons. This includes submitting requisitions for stock, as well as DTO requisitions for embarked aviation squadrons and ship’s departments. Stock replenishment policy afloat includes the computation of demand quantity during the past 6-,9-, or 12-month period. Use the endurance table in paragraph 6230 of NAVSUP P-485 to adjust the high limit, low limit, and safety level. When using the endurance table, determine the proper order and shipping time (O&ST) before selecting the high/low limit for SIM items. The authorized O&ST are as follows: . 0 (zero) days for deployed and nondeployed ships when items are readily available in SERVMART or tending ship throughout the following quarter. . 30 days for nondeployed ships in the United States, excluding Alaska and Hawaii. It is also 30 days for deployed ships when the items are available from stock points in Alaska, Hawaii, and outside the United States or from Combat Logistics Force (CLF) ships throughout the following quarter. . 75 days for deployed ships in areas other than Western Pacific when items are available only in the United States, excluding Alaska and Hawaii. l 90 days for deployed ships in Western Pacific when items are available only in the United States, excluding Alaska and Hawaii. The cognizant fleet commander in chief may authorize changes to the O&ST when it is considered 10-3
