Reschedule Out Delta

Can anyone confirm that they have gotten this to function in there system?

Also, it appears that Epicor ignores this on parts that are make direct. I have a part with a reschedule out delta of 30 and every make direct job is being told to be postponed such that the end date of the job is the same day as the shipment, even if the shipment is only a couple days later.

ARGH! These planning parameters are giving me a headache!
