Here you can enter a minimum quantity below which you do not want the program to propose an action to decrease the quantity on an existing order. The program then proposes such an action only when the quantity exceeds the amount that you enter in the field. No action is proposed if the quantity is equal to the amount that you enter in the field. You specify this quantity as a percentage of the lot size of the item.
You use a dampener in order to limit insignificant action messages when the program calculates a plan.
