The override logic that exists in convertible calculations checks if the MFP_CONV_CALENDAR column is set. If yes, then that calendar is used. If the column displays a NULL, then go to System Parameter 15 and set the source interface instance for the business calendar.
Specify the Business Calendar
Each entity can have a business calendar assigned by populating the MFP_CONV_CALENDAR column in the ENTITY_EXTENSION table in the RULES database.
Set the Business Calendar Override
Several system default settings are used for the anniversary period and frequency. These default settings are applied to all convertible funds for all convertible returns. However, if there are funds that follow a different conversion schedule, you can set entity level overrides for each of these parameters.
The MFP_CONV_FREQUENCY and MFP_CONV_PERIOD columns in ENTITY_EXTENSION table are used for overrides. If an override is set, then it is used in place of the system default. The MFP_CONV_CALENDAR column in the ENTITY_EXTENSION and ENTITY_EXTENSION_HIST tables are leveraged the same way as the other override columns.
Using the Business Calendar Override
After the convertible returns calculation process checks the MFP_CONV_CALENDAR override column at the same time that the other override columns are checked:
If the MFP_CONV_CALENDAR column is populated, then use that business calendar for convertible return calculations in conjunction with any applicable System Parameter settings used for convertible return calculations. In this case, this calendar is used in place of any selection in System Parameter 15. The calendar specified in the MFP_CONV_CALENDAR is used to adjust the baseline derivation of the conversion date.
If the column displays NULL, then proceed with current convertible returns processing and apply all applicable System Parameter settings, including System Parameter 15.
