attach a commercial invoice to copy 1) to the disbursing activity shown in the block titled “Agency Name and Billing  Address.” l Copy 4 is sent to the appropriate fiscal office for recording  of  obligations. Because SF 44 is highly pilferable, it is controlled by serial number. Refer to enclosure 2, chapter 5, of NAVSUPINST 4200.85 (series) for a sample SF 44. REQUISITION STATUS The purpose of a requisition status is to inform the requisitioner of the action being taken on their requests. Keeping an up-to-date status on all requisitions is part of the monitoring functions of an AK. Requisition status gives you the information needed for making decisions in the applicable job. For example, if the requested item is  not  available  for  issue,  a  similar  item  may  be cannibalized   from   other   equipment   to   fill   the requirement. On the other hand, if the item is available, other   unnecessary   effort   can   be   prevented.   The following text covers the procedures for maintaining the status on requisitions. TYPES  OF  STATUS Supply activities provide requisition status based on the Media and Status code of the request. The Media and Status code occupies record position 7 of the requisition. Appendix  A6  of  NAVSUP  P-437  provides  a  list  of Media and Status codes that you may use. Exception Status There are several situations that stock points use as a basis for providing an exception status. They are one, or any combination of, the following decisions made by a stock point. Material  obligation Procurement  for  direct  delivery Substitution Change  to  unit  of  issue,  stock  number,  or cognizance   symbol Requisition  rejected  for  specific  cause Referral  order Cancellation   acknowledgement l Any other circumstances that says the material will  not  be  issued  within  the  time  frame established for the priority of the requisition. 100% Supply Status The 100% supply status provides information on every  action  taken  by  the  supply  system  on  the requisition. It includes release of material for shipment, but not the mode of shipment and bill of lading number. The  stock  point  provides  100%  supply  status  for requisitions, depending on the Media and Status code used. Shipment Status The shipment status consists of data on the actual shipment of material. It includes the date and mode of shipment,  transportation  control  or  bill  of  lading number, and date available for shipment. SUPPLY  STATUS  FORMATS There are two types of formats for furnishing supply status. The first type is a standard format used to provide most  types  of  status  information.  The  second  is  a specific  format  used  when  the  material  is  being purchased for direct delivery to the requisitioner or supplementary  address. Standard Format The requisition status provided in standard format will have document identifier (DI) AE followed by a number or letter. The following paragraphs describe the data elements of status in standard format. The  record  positions  1-3  contain  the  document identifier.  Appendix  A4  of  NAVSUP  P-437  provides  a list  of  these  document  identifiers. The  record  positions  4-6  contain  the  routing identifier  of  the  activity  furnishing  the  status.  See Appendix A10 of NAVSUP P-437 for a list of routing identifiers. The record position 7 contains the Media and Status code from the requisition. The record positions 8-22 contain the NSN NICN or part number of the item. This field will include the CAGE and first 10 characters of the part number (if the part number has more than 10 characters). The record positions 23-24 contain the current unit of issue. 4-12
