Create a return authorization for the wrong item that was received and billed. This will reverse the effect of the item receipt and vendor bill on the item's average cost. 2. After the return authorization is approved, create an item receipt. This will reduce the quantity on hand and increase the quantity on order. 3. Then, create a vendor return based on the return authorization. This will reduce the quantity on order and will not affect the average cost since the return cost is the same as the received cost. 4. Now, you can create a new purchase order for the correct item. Please note that this process assumes that the wrong item has not been used or sold after it was received. If it has been used or sold, then additional steps may be necessary to correct the inventory and costing records. Also, remember to enable the account preference

Allow Overage on Item Receipts

(Setup > Accounting Preferences > Order Management) if you want to over-receive items.
