We recently added the Export Data and Corrective Actions reports to the Reports menu in Incident Track. They differ from all other reports in the menu in that they only operate on the current site in the primary site. The rest of Incident Track treats the primary site as an administrative layer that can access all other sites' data. One side-effect of the omission in these reports is that you can enter corrective actions for an incident through the primary site, but then are unable to see those corrective actions in reports run from the primary site.
Cassandra Rudy with MMA requested this feature to be added as well.
