To override restocking values for a retail product:
Right-click the Location row that you want to set to override.
From the shortcut menu, click Edit to display the Edit Restock window.
(Show picture)

Click the Override values radio button.
Enter a value for
Max Quantity
The maximum on-hand quantity. By default, if an item is to be reordered, the amount reordered will be the Max Quantity minus the Quantity on hand.
and
Min Quantity
The minimum on-hand quantity. By default, if the on-hand count is less than Min Quantity plus the Buffer Quantity, the item will be reordered.
Enter a value for
Buffer.
Buffer is the number of units (per inventory status) set as the "inventory forecast number" added to the Min Quantity to provide an adequate stocking level to serve needs while the reorder process takes place.
Click Save to keep your changes.
Notice that the row on the Restock tab now displays in black with the Max Quantity, Min Quantity, and Buffer Quantity shown.
