How do I bring back data greater than 6 months in Workforce Performance.Performance rating real time

Summary:

We've been told that the link conversation performance only captured data from the last 6 months of the creation date. When we investigated the report there is no filter anywhere that would have restricted the results to the last 6 months. Can we force 'Performance documentation creation date' to look for data greater than 6 months?

Thanks,

Chuck
