Hello

I regularly have invalid objects in several instances. I created a job that is scheduled every day to recompile all invalid objects in an instance.

But it's always try and error when deciding at which time to run the job. Unfortunately, I do not have enough application know-how to point out the cause, so I just solve the problem (that is done quick and comfortable with this workaround)

Is there a way to determine when objects become invalid?

Thanks for your responses Casi
