Use  record  positions  40-43  for  entering  the four-position  serial  number  of  the  requisition.  The document number assigned by the requisitioner will be cited in all supply and financial documents. Therefore, do not assign duplicate serial numbers on the same day. Positions 40 and 41 may consist of alpha or numeric characters. However, use G in the first position only for Not  Mission  Capable  Supply  (NMCS)  requisitions. Also,  use  G  for  Partial  Mission  Capable  Supply (PMCS),   Anticipated   NMCS,   and   Broad   Arrow requisitions.   Appendix   C   of   OPNAVINST   4790.2 (series) provides definitions for NMCS, PMCS, and ANMCS terms. Project code ZF7 signifies Broad Arrow requirements.  Broad  Arrow  is  the  requirement  for non-operational  ground  support  equipment  (GSE)  used in direct support of aircraft. Broad Arrow is a condition that is used when GSE is down and there is no backup GSE locally available. Requirements for material or services needed to correct a casualty report (CASREP) are indicated by a W in position 40. The remaining positions  of  the  serial  number  will  be  numeric (001-999).  The  SUADPS-RT  support  procedures provide a standard document numbering system for Special  Accounting  Class  (SAC)  207  activities.  The following  text  describes  the  recommended  assignment of some serial numbers. Aviation Fleet Maintenance (AFM) Charges Serial Number Assigned to D0-D9 Intermediate   maintenance   (work centers) E0 - E9 Organizational  maintenance  (squadron/ ship’s aircraft) Y0 - Y9 Intermediate/organizational mainte- nance Flight  Operations (FLTOPS)  Charges F0-F9 Squadron  and  ship’s  aircraft NMCS/PMCS/CASREP    Requisitions G0 - G8 AFM  requisitions G9 AFM  requisitions W0 - W9 Ship’s  CASREP  requisitions Stock  Requisitions 0001  -1999 Stink  requisitions Ship’s  Divisions 20-89 Assigned  to  different  divisions  of  the ship.   The   divisions   of   the   supply department use serial numbers 80-89. The  Aviation  Stores  division  (S-6)  uses 86  series  document  numbers. Use record position 44 for entering the Demand code. Demand code R (recurring demand) will result in the  inventory  manager  reinvesting  the  funds  to  replace the sales. Therefore, the next time a customer demands the item, it will be available. If the customer enters an N (nonrecurring demand), the inventory manager will not reinvest the funds unless the item needs replacement to cover other requirements. The following paragraphs describe the rules for coding demands. Assign   a   Recurring   Demand   code   (R)   to   all requisitions when the item is a replacement for stock or is in use. These items include equipage, repairable items, repair parts, and consumable. Some examples are stock  replenishment  and  preventive  maintenance material, such as oil and lubricants and general-use consumables. All requisitions for cognizance 0I and 1I material will have Demand code R assigned. Assign  Nonrecurring  Demand  code  (N)  to  all requisitions when the required item is not a replacement for an existing item in use or stock. Some examples of requisitions that need a Nonrecurring Demand code are initial stocks and initial outfitting requirements. Use   record   positions   45-50   for   entering   the supplementary  address.  The  requisitioner  may  use  this field to tell the supplier who is to receive material, status, or billing. When used for this purpose, record position 45 will contain the Service code. Also, record positions 46-50  will  contain  the  UIC  of  the  activity.  The requisitioner also may use this field for local controls. When used for this purpose, enter Y in record position 45 and any combinations of letters and numbers in record  position  46-50. Use record position 51 for entering the Signal code. The  Signal  code  serves  a  dual  purpose.  It  identifies  the activity to receive the material and the activity to receive the billing. Signal codes D and M are for free-issue items. Refer to Appendix A12 of NAVSUP P-437 for a list  of  Signal  codes  and  their  meanings. Use  record  positions  52-53  for  entering  the  Fund code. The two-digit Fund code was developed to bill an activity properly for the material received. Unless a requisition has Signal code D or M (free issue) in record position 51, enter the Fund code from NAVSO P-3013, Appendix II. Leave this field blank if the requisition is 4-4
