They should be used when they contain clues about a problem in the DB being monitored.

AWR report is taken and analyzed when there is performance problem in database.
ASH enables you to examine and perform detailed analysis on both current and histroical data often avoiding the need to replay the workload to gather additional performance tracing information.

My point is that if you know something about it, you can't NOT know what/when to use it.

>AWR report is taken and analyzed when there is performance problem in database.

So when do you think you use it and what for? Perhaps when there are problems reported?

The same scenarios. It depends on what data you have available.

A perfect example of an oxymoron. You know when to use what, but you want to know when to use that.
