Replenishment Settings for inventory
1. When the override tick box is on and the value is greater than 0, the MRP will always use this value(picture 1). Otherwise it will use what is on the warehouse item details - replenishment tab(picture 2). If there are values in both fields the stock items>manufacturing value will get priority.

2. When Min. order qty, Max Order Qty or Lot Size is greater than 0 (Picture 3) on the manufacturing tab, MRP will always use this value. Otherwise it will work on the Vendor settings (Picture 4).
