To use min-max purchasing:
In Product Maintenance and Product Location Maintenance, select Min/Max in the Buying Method field for products you want to use with min-max purchasing. You must also enter a primary supplier, minimum stock level, maximum stock level, and internal buyer. When available inventory falls below the minimum stock level, a purchase order is recommended. The purchase recommended amount will be made to increase inventory up to this amount. The minimum purchase quantity optionally may be entered. This quantity is the minimum amount that can be recommended for purchase for this item. A purchase increment optionally may be entered. Any purchase quantity will be in multiples of this increment value.
In Min-Max Buying Maintenance, create a buying ID for the grouping of buying that the customer wants. For example, A Buying ID could be All Suppliers for one particular buyer.
In Min-Max Buying Select, create buying information for the buying ID you created in step 2. This procedure preprocesses a specific buying ID that has been created in Min-Max Buying Maintenance.
In Min-Max Buying Recommendations, display all products that were preprocessed in Min-Max Buying Select. You can make changes to the recommended products, export the data to Excel, and import data from Excel. Finally, click the Create button to create purchase orders for the displayed products.
In Purchase Order Maintenance, review and edit the purchase orders, then select the Ordered check box for each order.
