Performance Analytics regularly
collects scores from your data on an ongoing basis. When you first set up Performance Analytics for an
application, or when you create new indicators or indicator sources, run historical data
collection to collect scores on your existing data. Historical data collection enables
you to analyze data that existed prior to setting up Performance Analytics.
historical data collection job deletes any previously collected data for the periods
and the indicators that the job covers. It does not delete data from outside that
date range or for other indicators.
