obtained by input of a stock number inquiry (document
identifier X90). The data in the MRF is kept current by
the application of transactions during update processing
and by the application of change notice actions.
Requisition Record File
The Requisition Record (RQN) File is an active tile
containing records for outstanding and completed
requisitions originated by or for the ship. Completed
requisitions may be removed from the RQN File by
using the Requisition History File Process (RHISP)
utility. RHISP will strip completed requisitions from
the current requisition file and add them to the
Requisition History File (RI-IF). Each requisition
record consists of the card images of all status, follow
up, and receipt transactions processed under the
particular document number. Change notice actions
which apply to the MRF also apply to the RQN File and
become subrecords where applicable. A requisition
record is initially established at the time a requisition
document identifier (DI) (e.g. A0A) is processed in an
update. The computer rejects any attempt to establish
duplicate document numbers. The computer program
allows a maximum of 32 subrecords for each
requisition. A printout of a RQN record and related
information may be obtained by input of a document
number inquiry (DI X90).
Numbers File
The Numbers (NBR) File is a history file which
contains a record of stock number changes and
cross-reference data. Stock number changes are
automatically recorded in the NBR File at the time
change notice is processed. Records are contained in
this file cross-referencing the following:
1—New NSN to old NSN and vice versa
2 —Part number (exceeding 15 positions) to local
stock number and vice versa
3—New part number to old part number and vice
versa
4—NSN to description and vice versa
5 —Part number to description and vice versa
6 —Local stock number to description and vice
versa
Inquiry into the NBR File may be made by a Numbers
File Inquiry (DI X90). A numbers inquiry will produce
a listing of the basic numbers record and all related
cross-reference subrecords. DI 082 may be used to
obtain a complete printout of the Numbers/
Cress-Reference Listing.
Financial Master File
The Financial Master File (FMF)is a series of tables
and counters that generally correspond to financial
reports and records.
These tables are posted during
update processing. The reports are produced from the
computer as required by stock control personnel.
Maintenance Data Collection File
The objective of the Maintenance Data Collection
System (MDCS) is the collection and reporting of
maintenance-related data into the 3-M Systems by the
use of a TDA91 tape.
Equipment maintenance
information (job control number, equipment
identification number, etc.) is obtained from the supply
documents for reporting into the 3-M Systems. This
information is obtained from the following
maintenance-related documents:
1. Issue documents
2. DTO requisitions
3. Receipts
4. Departmental turn-ins
5. AB , AS , and AE supply cancellation status
The only tape file in the system is the Maintenance
Data Collection (MDC) File. The Maintenance-
Related Transaction (MRT) in the MDCS is the same as
the Transaction Tape (TRN) in the supply system. The
MDC File contains data collected by the system and
subsequently output as TDA91 tape.
MANUAL FILES
Manual files provide control over transactions
which have not been completed. They are also a point
of assembly for transitions which are to be processed,
and they provide various system users with history or
reference files on completed transactions. These files
are explained below.
Keypunch Assembly File
The Keypunch Assembly File consists of source
documents which are to be sent to Data Processing for
keypunching. This file is maintained in the Stock
Control Division. The documents are assembled in
11-5
