5.3.19.1 File Organization
The table below identifies data elements by which the file is
sequenced and summarized in each timespan. N/A indicates
that the file is not supported in a timespan. At the DETAIL
level, data is sequenced but not summarized.
NOTE: The timespans in which a file is supported are
defined by each installation when CA MICS is installed.
Therefore, this table has been generated as part of the
installation process to accurately reflect the CA MICS system
at your installation.

NOTE: This file was generated with ESSENTIAL=ALL
option in effect. All data elements defined in
the file are generated.
NOTE: This file was generated with DERIVED=DEFault
option in effect. Whether data elements are
kept on the file on auxiliary storage or not
is controlled by the complex definition of the
DERIVED option.

5.3.19.2 Data Elements List
The table below identifies data elements contained in this
file. The entries for each data element are:
TIMESPAN: Defines the timespans in which the data element
is supported. The timespans are indicated by
the letters "XDWMYT" as follows:
X - DETAIL
D - DAYS
W - WEEKS
M - MONTHS
Y - YEARS
T - TABLES AREA
. - File is not supported
The timespan field also indicates Essential Elements with
the letter E, if applicable.
DATA ELEMENT: The data element name.
DATA ELEMENT DESCRIPTION: The data element's long name.
The timespans in which a data element is supported are
defined by each installation when CA MICS is installed.
Therefore, this table has been generated as part of the
installation process to accurately reflect the CA MICS
system at your installation.
GENERATION DATE: Wed, Apr 18, 2012
Note: Essential data elements are identified by an "E"
under the Timespan asterisk (*) column.

5.3.19.3 Usage Considerations
Special considerations or techniques related to using the
SCPSRS file are provided below.
1. Care must be exercised in using the special date and time
data elements contained in each CA MICS file. As the
file's granularity decreases in higher timespans, certain
fields lose significance; they should not be used in
those cases.
o HOUR should not be used in MONTHS.
o DAY and DAYNAME should not be used in WEEKS, MONTHS.
o WEEK should not be used in MONTHS.
2. ENDTS and STARTTS, when appearing in the DAYS, WEEKS, or
MONTHS timespans, bound the span of time over which the
data has been summarized. STARTTS is the lowest date and
time, and ENDTS is the highest date and time for the data
summarized. These data elements have different meanings
when used in the DETAIL timespan versus the DAYS, WEEKS,
and MONTHS timespans. Their purpose in DETAIL is
described below:
o STARTTS represents RMF recording interval start time.
o ENDTS represents RMF recording interval end time.
