The Gallery Manager
maintains an internal index, or cache, of the reports that are stored
on the SAS Content Server. The reports that are associated with the
Gallery Manager are only those that are generated by SAS IT Resource
Management report jobs. When SAS IT Resource Management report jobs
run successfully, the cache is updated correctly. However, in some
cases, such as network connection failures, you might not be able
to see new reports. Similarly, you might see a 404 error message that
refers to reports that were deleted because the cache was not updated
correctly.
