MILSTRIP status documents contain a document identifier and a routing identifier. These identifiers denote the type of document and the sender of the status data. Supply status documents contain a Status code in card columns 65 and 66. For a current and complete description of MILSTRIP Status codes, refer to NAVSUP Publication 485. Shipment status documents contain information regarding shipment. This includes date of shipment, mode of shipment, transportation control number, date available for shipment, and port of embarkation. Requisitioners need not always accept the rejection/cancellation of a requisition as the final word. In some cases, requisitions are rejected/canceled because the RDD cannot be met. When a later RDD can be provided, the requisitioning unit should submit a MILSTRIP modifier with a request for reinstatement in the remarks section. Occasionally, the quantity requisitioned is questioned by the processing activity. This may happen when the quantity requisitioned exceeds the allowance or is not on allowance. Questions of this nature should be evaluated promptly and a reply forwarded to the processing activity. When the requisition is justified, say so and why. Expediting Requisitions Normally, ammunition requisitions are processed for delivery to the requisitioning activity by the ammunition supply system without problems. However, requisitions do become lost or delayed. To minimize this situation, there are several methods that can be used to review and expedite requisitions. These methods include follow-up, priority increase, and special assistance. Aggressive submission of a MILSTRIP follow-up on an outstanding requisition is the first and best method of ensuring the requisition is not lost. All requisitions have some type of status requirement. Stock points and inventory managers are responsible for providing this status, and requisitioners should expect it. MILSTRIP follow-ups should be submitted to the last known Navy holder after 14 days have elapsed since submission of the requisition or the last follow-up. You should continue to do this until a status is received. A follow-up should also be submitted whenever notification of backorder status (Status codes BB, BC, BD, or BP) has been received and there is an indication that delivery will not meet the RDD. Follow-up every 14 days until more positive status or confirmation of the delay is received. There are three types of follow-up; each one is distinguished by a specific document identifier. When only the current status of a requisition is needed, you should use Document Identifier code AF1. A follow-up using a three-position document identifier in the code AT (series) is submitted when you are requesting the current status of a requisition. This follow-up serves as a replacement requisition when the supply source has no record of the previously submitted requisition. Activities located in CONUS should use Document Identifier code ATD, and activities outside CONUS should use AT4. The AT (series) Document Identifier codes are used only when status has not been received by the requisitioner. An AFC Document Identifier code is used to improve the estimated shipping date (ESD) when an unsatisfactory ESD has been received from the supply source. A second follow-up method is to personally contact the holder of the requisition. This method should be reserved for more serious problems. It should NOT be used in a routine manner because it usually involves an extraordinary amount of time and effort for all personnel concerned A third method of expediting requisitions is to raise the priority of the requisition. This can be done only when the F/AD is upgraded or when the urgency of the requirement increases (UND designator is raised). Normally, ships and units not deployed are assigned F/AD III. However, F/AD II is assigned to ships and units 60 days before and during deployment. Accordingly, requisitions submitted more than 60 days in advance of deployment use priorities authorized for F/AD III. When deployment is less than 60 days away, requisitioners may raise the priority to one of those authorized for F/AD II. Usually, when the priority is raised, the requisition rates a different M&S code. While the requisitioner has the principal responsibility to monitor, follow-up, and expedite requisitions, there may be instances where the requisitioner is unable to do this. In these instances, assistance can be requested from CINCLANTFLT (for fleet requisitions) or from NOC (for requisitions of a shore activity outside CONUS). Requisition Changes When the need arises to change some part of a requisi- tion, there are certain procedures you should follow. These procedures are discussed in the following paragraphs. PRIORITY, MEDIA AND STATUS CODE, AND RDD CHANGES.— MILSTRIP provides a procedure for changing the priority, Media and Status code, and/or RDD of a requisition when either the F/AD or UND is 17-20
