Normally option rates are determined for the month. In rare special cases, it might be necessary to change the option rate method within a month. In that case, you are required to perform option rate calculations on a daily basis. You can use report RFREIT_OPT_RATE_DAILY for that purpose. Report RFREIT_OPT_RATE_DAILY calls an update run of report RFREIT_OPT_RATE_CALC for each day of the period you select. It is not possible to run report RFREIT_OPT_RATE_DAILY in simulation mode. For a simulation, you can use report RFREIT_OPT_RATE_CALC with an appropriate key date.
Note that calculating option rates to the day generates an extremely large volume of data. Therefore, we very strongly recommend that you archive the data on a regular basis (transaction SARA, archiving object REFX_OR).
