VCA ACCOUNTING Statement

Valid values for timespan are DETAIL and DAYS. The default value is DAYS. This parameter specifies to VCA when it should invoke the accounting routines generated by
MICS Accounting and Chargeback
Option.

ACCOUNTING Timespan
DAYS results in VCA presenting a summarized observation to the accounting routine. The sequence/summary elements of the VCA file at the DAYS timespan are used to create a summarized observation that represents all DASD space occupied by that control break.
DAYS allows reasonable flexibility in qualification pricing in the accounting routine. For example, assume the sequence/ summary elements at the DAYS level are:
   SYSID    VCAACT1   VCAACT2  DAADSTYP  DEVTYPE    STORSTGC STORMGTC  YEAR     MONTH     DAY
MICS
summarization routines will create a single observation for data sets whose values for these fields form a unique combination.
To build on this example, it follows that all data sets that have the following will be summarized into one observation:
SYSID='ASYS'; VCAACT1='DIV100'; VCAACT2='DEPT22'; DAADSTYP='VS'; DEVTYPE='3390-2'; STORSTGC='NEVCACHE' STORMGTC='TESTDATA'; YEAR=90; MONTH=07; DAY=24;
Accounting qualification techniques and algorithms allow for pricing of DASD space by applying rates based on the actual values in these control or sequence elements in the above example.
Note that VOLSER and DSNAME are absent from the list. If you need exception level pricing by having the accounting routines examine either VOLSER or DSNAME (or any other character data element not in the SORT key of the DAYS timespan), consider coding ACCOUNTING DETAIL here in VCAOPS.
DETAIL causes VCA to invoke the accounting routine to price a data set at the DETAIL timespan. Each data set can be examined by the accounting cost algorithms and all data elements carried at the DETAIL timespan are available for inspection by the accounting code.
To continue with the example above, VOLSER could be tested and a special rate could be applied to some DSNAMEs if they appeared on a given VOLSER.
The choice of DETAIL versus DAYS on this parameter should be worked out with the people responsible for the
MICS Accounting and Chargeback
Option. Since there will naturally be more observations at the DETAIL timespan than at the DAYS level, it follows that DETAIL will increase the space required for cycles of the accounting journal files (ACTJDA01, ACTJVS01, etc.). There is a one-for-one correspondence between the number of observations on the VCA file and the accounting journal file that holds the charges developed from that VCA file.
