The supporting documentation may vary by circumstances but should consist of the following documents: 1. For adjustments or reversals requiring preliminary research, a checklist of actions taken during preliminary research such as search of adjacent locations, research of unposted or erroneous transactions, or verification of catalog data. 2. For adjustments or reversals requiring causative research, the following is a list of the necessary supporting documentation: l l l l l l l l l A checklist of actions taken during preliminary research Receipt, issue, or transfer documents relating to the investigation Cumulative transaction ledger or master stock record probes Survey documents Unmatched listings Repair parts petty officer (RPPO) or AIMD logs Mandatory turn-in repairable (MTR) or carcass tracking documents (including beyond capability maintenance [BCM] log) Detailed list of DLRs Any other supporting documentation Inventory Count Procedures A complete and correct item count is basic to a physical inventory which, in turn, results in greater stock record accuracy and better inventory control. Detailed procedures for the inventory count afloat are described in Automated SNAP 1 Supply Procedures, NAVSUP P-567, and Afloat Supply Procedures, NAVSUP P-485. The inventory options available for use on SUADPS-RT ships readily adapt to the inventory schedule and needs of the inventory supervisor. In automated ships, the inventory supervisor can tailor the inventory in anyway that fits the applicable needs. You should familiarize yourself with all the applicable document identifiers to perform a specific task. Recording Inventory Results on The results of physical inventory must be recorded the manual or automated files used by the activity. For manual procedures, refer to NAVSUP P-485. For automated procedures, refer to SUADPS-RT support procedures or other supporting publications. Inventory Accuracy Standards Upon completion of the physical inventory and reconciliation of the stock records, the count and adjustment documents must be reviewed. The documents are reviewed to determine the number of items inventoried and the number of location or quantity errors both corrected or adjusted. As a minimum, an accuracy rate of 90 percent is considered acceptable (refer to TYCOM instructions for additional guidance on validity standards). If the accuracy rate is below standard, the supply officer immediately initiates action to ensure more effective maintenance of stock records. Location Audits The purpose of the location audit is to verify that material in storage locations agree with the location in the stock record. A location audit should be scheduled so that it is done just before the scheduled inventory of a particular storage area. All storage areas (100 percent) must be audited on an annual basis. A well-managed location audit program (LAP) reduces inventory efforts and improves the supply effectiveness and inventory accuracy. The LAP also improves the use of all available storage space. PROCEDURES.— Location audit procedures are contained in NAVSUP Instruction 4440.185, TYCOMs’ directives, and NAVSUP P-567. The stock number, location, unit of issue, and shelf-life expiration date are verified during a location audit. LOCATION AUDIT VALIDITY.— The location validity rate is computed upon completion of a location audit for a particular storeroom or storage area. The accuracy rate for a location audit is 98 percent. The rate is computed by auditing 5 percent of the locations involved and subtracting the number of erroneous locations from the total number of locations audited. Then, divide the difference by the total number of locations audited and the result is the accuracy rate. As an example, for 850 locations validated with 17 errors, the following applies: 850-17=833 833 + 850= 98% accuracy rate An accuracy rate of less than 98 percent for a particular storage area is considered unsatisfactory and 5-18
