MRP Exception message for Excess production quantity

Originally, there is a demand for a common item material A 1500

One work order is opened for this grouped demand

Grouped Demand: 1500

Work Order QTy: 1500

Due to a drop in demand, the demand fall to 1200

At this time, will any MRP exception raise to suggest the order to reduce the scheduled quantity to 1200?

If there is way to do so, what should I set to achieve this requirement?
