ACT Rate Simulation
MICS Accounting and Chargeback
provides rate simulation to reduce the manual effort required to determine the magnitude of rate changes. This facility has no provisions for calculating optimal rates, but can calculate the effect of a proposed rate change.micsrm140
The rate simulation facility recalculates charges by multiplying the existing quantities from generation 0 of the ACTAUDIT DAY1 file by the new rates you supply. Since the ACTAUDIT file is built from the journal files, no new billable elements (COMPCODE statements) may be input to the simulation process. Also, the effect of using the SELECT, EXCLUDE, SYSID, SUBSYSID, and COSTCTR statements as input to the simulation depends on the way these statements are specified in the rate table that creates the journal files used as a basis for the simulation.
For example, if a given work unit is excluded from charging via the EXCLUDE statement when the ACTAUDIT files are created, removing it from the EXCLUDE list for the simulation will have no effect because no data for that work unit is present on the ACTAUDIT file. Similarly, if a site has four systems, but only three of them are specified via SYSID statements (no SYSID *ALL statement was present), coding a SYSID *ALL statement for the simulation will not take into account the effects of the system that was initially excluded. Conversely, because the prerequisite data is present on the ACTAUDIT file, if a SYSID *ALL statement is specified when the ACTAUDIT files are created, each system can be charged separately in the simulation by supplying the appropriate SYSID and COMPCODE statements.
The following steps are required to perform a rate simulation:
- Enter the Rate Simulation parameters. Refer to the online tutorial for the Rate Simulation panel (MWF;4;2;4;5;2;1) for help coding the parameters.Note:The rates in the Current Rate column must match the rates in the Audit file or the simulated rates will not be used.
- Submit prefix.MICS.CNTL(ACTRTSIM). You are automatically placed into ISPF Edit when the rate simulation parameter is entered or modified. You can modify the JCL to use an ACTAUDIT file other than the default DAY1 file.
