Another way of generating a report is one can query DBA_hist_snapshot to find the snap id for the interval you are looking for.

@?/rdbms/admin/awrinfo.sql – Script print AWR information like space usage by AWR, subset of AWR snap ids, Automatic Database Diagnostic Monitor (ADDM), Active Session History (ASH) information.
