Hello Tony
The function of Demand Planning is to ensure an optimum supply of inventory throughout. The level of inventory must be maintained such that it’s not surplus & at the same time inventory should not be too short to run into delivery delays. With help of this functionality we can avoid the excessive storage. To take the Demand fluctuation into account, Dynamic Safety Stock scenario can be incorporated. This method of planning is based on the precise that there is constant change in the average consumption which can be taken into account by MRP.
So every time the MRP is run this change in the average consumption is taken into account in the planning run and as a result the inventory quantities are recalculated.
In your case you want to avoid the average requirement and want to set as fix stock qty requirement, will suggest you in your case to use the Stock quantity. Because it is not possible in Dynamic safety stock calculation with coverage profile
Only option you have to use Dynamic safety stock with coverage profile.
You can set Min, Max and Target level stock so system will calculate the requirement as within range and add the additional qty which is minimum.
