I've just discovered that the projected value of our work orders is often changing, what would cause this system generated change and how do we stop it from happening? In this instance it looks like it stopped updating when the period closed and were using average costing...would it update each time the average cost of the items used in the build changed? Is there a setting somewhere that we can tell it to stop doing that, the value of the item at the time of build is what should be used and locked.
