Data Block C maybe left blank at the discretion of the supply officer, or it may include the noun name of the requested item. Data Blocks D-F (Editing data) should be blank. Use  record  positions  (CC)  1-3  for  entering  the document  identifier.  Appendix  A4  of  MILSTRIP, NAVSUP-437,   provides   a   listing   of   Document Identifier  codes. Use record positions 4-6 for entering the Routing Identifier code. This code identifies the activity that will receive the requisition. This is a mandatory entry except when  the  ship  will  issue  the  material  to  fill  the requisition. The Routing Identifier code entered in these positions must apply to the activity shown in data block A. See Appendix A10 of NAVSUP P437 for a list of Routing  Identifier  codes. Use record position 7 for entering the Media and Status  code.  This  code  signifies  the  type  of  status required, the activity to receive the status, and the method for sending the status. See Appendix A6 of NAVSUP P-437 for a list of Media and Status codes. Use  record  position  8-22  for  entering  the  item identification number, national stock number (NSN) or Navy item control number (NICN) The stock number field will not include such data as cognizance symbol and  material  control  codes.  When  an  item  has  an assigned NSN, enter the federal supply class (FSC) in record position 8 through 11. Enter the NATO code and the  national  item  identification  number  in  record positions 12 through 20. Enter the special material identification code (SMIC) in record positions 21-22. When required, enter the weapons systems designator code (WSDC) in place of the SMIC for high priority requisitions. The most common NICNs authorized for entry in MILSTRIP requisitions are stock numbers for forms, publications,  and  parts  kits.  Other  authorized  NICNs include the control numbers assigned by the inventory control points or item manager. Enter the first four digits of the NICN in record positions 8-11. Enter the NICN code LL in record positions 12-13, and the remaining characters in record positions 14-20. Use record positions 23-24 for entering the proper abbreviation   for   unit   of   issue.   Appendix   A23   of NAVSUP P-437 provides a listing of unit of issues. Ensure the unit of issue is correct by matching it with the required quantity. For example, you will receive 100 of the items when you put 00001 in the quantity field and the unit of issue field is HD (hundred). You will also get 100 of the items when you put 00100 in the quantity field and the unit of issue for the item is EA (each). If you put the wrong unit of issue of EA with 00100 in quantity field, you might get 10,000 of the items. This happens when the unit of issue gets corrected to HD but the quantity is not adjusted to 00001. Use record positions 25-29 for entering the quantity of the needed item. For a quantity of 99,999 or less, enter the total quantity required. If the required quantity is less than five digits, precede the quantity with zeros to provide a five-digit entry. If the quantity is more than 99,999, prepare and submit additional requisitions for the  remaining  amount. Enter specific instructions in the Remarks field for items needed in a minimum length, size, or other special measurements  when  no  advice  code  applies.  For example, “Minimum length acceptable is 10 feet.” Enter C9999 in the Quantity field for continuing and annual  requirements.  Use  this  for  requisitions  that  will result in multiple receipts of material or services. Some of  these  are  requirements  for  gasoline,  telephone service,  or  copying  machine  service.  See  NAVSO P-3013,  paragraph  4102-7,  for  information  concerning the use of C9999. Use   record   positions   30-43   for   entering   the document number. The document number includes the requisitioner’s service designator code and UIC, the Julian date of the requisition, and the serial number of the requisition. In record position 30, enter one of the following service  designator  codes: R - for Pacific Fleet operating units V - for Atlantic Fleet operating units N - for shore activities. Fleet operating units may use this code when specifically authorized. In record positions 31-35, enter the UIC of the requisitioner.  This  is  the  chargeable  activity  when record positions 52 and 53 cite an End-use Fund code and the Signal code is an A or J. In record positions 36-39, enter the Julian date of the actual transmission of the requisition to the supply source. The first position of the Julian date represents the last digit of the calendar year. The last three positions show the numeric consecutive day of the calendar year. All  government-issue  calendars  show  the  numeric consecutive day of the calendar year. For example, Julian  date  3274  represents  1  October  1993. 4-3
