quantity  is  lined  out,  but  not  obliterated,  and  the quantity actually received is marked directly below the lined-out  quantity.  The  word  Discrepancy  is  stamped or  written  on  the  document.  Depending  upon  the circumstances  of  the  exception,  the  material  is  placed either in stock or in a temporary holding area pending disposition. The marked document is then forwarded to  the  financial  inventory  control/clerical  function section  for  exception  processing. Material Turned in to Store Navy material returned nom the customer to stock points has traditionally been called material turned into store  (MTIS).  Stock  points  carry  material  in  stores accounts   such   as   Navy   Stock   Account   (NSA)   or appropriation  purchase  account  (APA). MTIS is used primarily to take ready for issue (RFI) turn in from customer activities and return them to stock to meet anticipated requirements. When a retail stock point does not carry the MTIS in stock, a formal inquiry procedure   to   declare   the   material   excess   to   the wholesale item manager via the DOD material returns program  (MRP)  is  initiated  according  to  instructions  as outlined in NAVSUP P-437, chapter 2. MTIS is placed in local stock when the item is within  the  authorized  retention  limit  of  the  activ- ity. MTIS   SCREENING   AND   IDENTIFICA- TION.—  A  material  screening  and  identification section should be available at all shore activities for MTIS. MTIS is held in this section during the screening and   identification   process.   During   the   screening process,  material  received  with  proper  documentation and  packed  in  a  professionally  packaged  container  is inspected using the same procedures as a routine receipt from other sources. Effective  MTIS  operation  requires  the  use  of technical  reference  material  for  identification  process and decision making in determining when to place the item(s) in stock (with or without credit), when to send an excess inquiry to the item manager, or when to determine that the item has no use to the Navy and qualifies  for  transfer  to  the  DRMO.  The  following resource  documents  should  be  available  for  personnel performing  the  MTIS  screening  to  use  in  this decision-making   process:   Management   List- Consolidated  (ML-C);  Master  Cross  Reference  List (MCRL);  Master  Repairable  Item  List  (MRIL); Navy  Item  Control  Number  (NICN)  to  National Item  Identification  Number  (NIIN);  and  the  demand history  record  (either  microfiche  or  printout)  when available. Upon  receipt  of  MTIS,  receiving  personnel should verify quantity and check in the material as follows: l l Release a receipted copy of the turn-in document to the representative of the activity turning in the material (when such representative is available and has provided one additional copy of the DD Form 1348-1 for this purpose). Attach  a  minimum  of  three  copies,  and  any additional  available  copies  of  the  DD  Form 1348-1, to the material and forward to the area designated for screening and identification, if required. SCREENING  DETERMINATION.—  MTIS is identified and classified under one of the following categories   as   described   in   the   following   infor- mation: For  material  identified  by  federal  supply  class  or federal supply group in an RFI condition and for which the instructions provide that the material will be taken up in stock, the annotation Ready for Issue (RFI) is made on the receipt document. For mandatory turn-in repairable (MTR) material that is not in an RFI (NRFI) condition, the MRIL should be used to identify the appropriate MTR processing activity  where  the  material  will  be  shipped.  However, activities   supported   by   a   Hub   must   ship   NRFI retrograde  via  the  ATAC  Hub. Material not required for stock, regardless of its condition upon receipt, is subject to an inquiry from the wholesale manager for disposition and held pending reply. For material determined to be scrap, the annotation Excess-Dispose  of  Scrap  is  applied  to  the  receipt document. The decision to send any material to the DRMO  should  be  considered  very  seriously  for other  than  valid  scrap.  Any  items  in  doubt  should  be referred  to  the  inventory  control  officer  for  final determination. When proper classification of the material has been determined, a minimum of three copies of the DD Form 1348-1 for each classification of material should be marked  with  one  of  the  descriptions  discussed  above. A copy of the DD Form 1348-1 must be attached to the 3-10
