I am receiving hundreds of these types of error everyday. Everytime I check the report schedule the report exist in the same location. I have attempted to refresh the schedules with no luck. Any ideas on how to correct this problem?
It is hard to say where the error is coming from. Could you have a custom task that is referencing a file that no longer exists? You may need to submit a support call and send your support files so someone can have a look at them.
