The Inventory screen is used to enter all inventory data and to view the records afterward. The only requirement is that each item must have a unique Local SKU. A Local SKU is the part number you use to refer to an item in your store or stores. A Supplier's SKU is the part number the item's supplier uses to refer to the item. Because an item can have more than one supplier, an item can have more than one Supplier's SKU. If you wish, you can use a Supplier's SKU as the Local SKU.
Follow these steps to enter an item into inventory.
Go to the Main Menu>Maintenance Menu>Inventory & Supplier's tab> Inventory.

Complete each field on the Product Info tab as required.
Notes:
A Single Unit SKU (bottom left-hand corner of the form) is assigned to the individual piece that, in multiple quantities, makes up a lot. The lot has its own Supplier's Lot SKU (bottom right-hand corner of the form in the Purchasing in Quantity Lots section). When you create a purchase order the Single Unit SKU is displayed with the quantity needed to complete a lot by default. To display the Lot SKU on purchase orders, click For Purchase Orders, order: This SKU.
The POCalcMethod parameter in the Purchase Orders group determines how the quantity to order is calculated when items are added automatically to purchase orders. The setting of the POCalcMethod parameter determines which fields are displayed on the Inventory screen:
Order Quantity displays Reorder Qty & Reorder Point fields
Target Quantity displays Target Qty. field
Delayed Target displays Target Qty. & Reorder Point fields
The Target Qty. is the quantity you wish to have in inventory at all times. For example, you want 10 pieces of an item on the shelf at all times. You sell 2 pieces and now you have 8 pieces on the shelf. The purchase order system automatically reorders 2 pieces to return the stock level to 10.
The Reorder Qty. is the number of pieces ordered automatically when an item reaches or drops below its Reorder Point. For example, if an item drops below its reorder point of 2 (there are 2 pieces on the shelf and you sell 1), then the system orders the reorder quantity or the number of pieces on backorder, whichever is greater.
The Delayed Target setting works similarly to the Target Quantity setting except that the system does not place an order until the inventory level drops below the Reorder Point. For example, your Reorder Point is 2. Your Target Qty. is 10. You sell 2 pieces and now you have 8 pieces on the shelf. The purchase order system does not place an order until the inventory level reaches 1, in which case it orders 9 pieces to return the stock level to 10.
The published weight (Published Wgt.) is the weight displayed for your customers. The Actual Weight is the weight used to calculate shipping. Enter these weights in generic units, i.e. for an item that weighs 7 pounds, enter "7".
Click in the Drop Ship checkbox if you do not stock the item and you ship it directly from your supplier to the customer.
Click in the Ignore QOH checkbox to indicate an item is always in stock.
Complete the fields on the other tabs as necessary.
Click the Close button to exit the Inventory dialog box.
