Procedure 6-12
Recover AMA data from DIRP - DIRP block number not known
Step Description
1 Contact the data center and determine the
time frame of the missing AMA, the
sequence number of the last DPP block the
data center received before the DPP outage,
and the first sequence number received
following the DPP outage. The sequence
numbers referred to here are DPP reference
numbers, not DMS or Data Center assigned
numbers.
At the MAP enter the following commands to
see if the DPP sequence numbers are
available to display from the DPP disk:
>MAPCI NODISP;MTC;IOD;DPPAMA
>RECORD START ONTO <printer>
>IDXMAINT EXAMINE AMA PACKED
<first seq number>
>IDXMAINT EXAMINE AMA PACKED
<last seq number>
If the above commands are successful, the
DPP outputs the requested AMA data
blocks. If BOTH blocks, first and last, were
printed out, continue to step 2. Any blocks
not output by the IDXMAINT command must
be provided by the data center before
continuing.
2 From each of the blocks of AMA data, one
record is required. In one block, locate an
"AA." Immediately following the "AA" is a
Structure Code. Using an NTP, break the
record down into the individual fields that
make up a record. For BCS31 or above,
use NTP 297-1001-830. For BCS30 and
below, use NTP 297-1001-128. An
example is below.

Notes
The first seq number may not be available
depending on the specific DPP fault.
If NTP 297-1001-830 is not available, NTP
297-1001-128 can be used to decipher
most records regardless of the BCS level.
