Contact policies determine when and for how long an action or a group of actions should no longer be shown to the customer. For example, if a customer views an ad for an action five times without responding, the add will no longer be shown to that customer over the next seven days. Suppressing or pausing an action prevents over-saturation by limiting the number of times that a customer is exposed to the same action.

1. In Dev Studio, click ConfigureDecisioningDecisionsData SourcesInteraction History Summaries.
   Note: Previously, when adding a new tracking period, you would use Action Outcomes for the past 7 Days or Action Outcomes for the past 30 Days rules. In 8.7 release, this method is deprecated. Use Action Outcomes by Channel dataset. While upgrading to 8.7 version, it is recommended that you remove these two data sets. For more information, see Removing deprecated Action Outcomes data sets.
2. Open the Data-pxStrategyResult class.
3. Create an Integer property CountOverNDays, where N is the number of days.
   Note: Only days are supported.
   1. In the Advanced tab, check Do not save property data under Persistence.
