Configure the amount of time that the aggregation service retains data for each organization:
In Reporting and Analytics, navigate to the Production Management portlet, and then click the Agg. Retention tab.
If you do not have the Production Management portlet on your sidebar, add the Production Management portlet from the Portlet type to your role, and then log back in to Reporting and Analytics.
Double-click the Retention Months column for the organization you want to configure, enter the number of months for data retention, and then click Save.
