Manage Date Rules

You can use the Date Rules workspace to add, view, and edit date rules. Date rules determine the date (or date range) that filters data used for an associated process. For example, date rules are used to calculate relative dates, that is, dates in relation to the current cycle effective date. You can assign a date rule to block stale vendor data from use when you define the data strategies.

Date Rule Example

You can use date rules for processing data strategies for time-sensitive reference data types such as Schedules. You can also use date rules to control when vendor data is consider too stale for composite use.

For example, assume that you are processing composited securities for an effective date of 1/1/2018 and wish to exclude vendor data that is more than 35 days old. You can assign a date rule to the data strategy that calculates the relative date 11/27/2017 and then blocks all data older than 11/27/2017 from the 1/1/2018 compositing process. In effect, only the most recent vendor data within the calculated 35-day window is composited and all older vendor data is ignored.
