If you track your products by serial, or lot number (or both) you can see the report in the inventory module.
Inventory > serial/lot number
Here you will see all the products that you have on hand, that you track by serial or/and lot numbers.
The displayed columns are:
UOM (Unit of measure)
Expiration date (of a Lot number)
You can search your product by SKU or a Product description
Quantity on hand will show you all the quantities you currently have in your stock.
While 'show all' will show you even sold items with serial/lot numbers. This way you will easily see which serial/lot numbers you have sold.
You can also open the report by a product from the product window.
Open product > reports > serial number/lot number
