How to manage exceptions for which action cannot be taken?

We have not used the exceptions in ASCP until now and we want to start using them to bring greater efficiency to our planning process.  Our planning is currently unconstrained, and we run the plan once daily.

In the process of validation we find that the system is performing well.  We still have some data issues which will reduce the number of exceptions, but increasingly, most of the existing exceptions are execution problems.

The question is what to do when we research an exception, confirm it is valid, and determine there is nothing that can be done about it?  The exceptions are valuable and should be reviewed, so I want to quickly identify the ones that are new today and investigate.  If I can resolve them then they won't be back tomorrow, but if I have hundreds that occur every day, and most of them I cannot resolve, the process of reviewing exceptions will take much more time than it should.
