Thank you for your reply Greg. Correct me if I am wrong, but, in inventory control, the lot number is stored with the purchase receiving transaction. In QB the Lot number is entered on the purchase receiving transaction. The lot number is then stored with the inventory quantity on hand in a "lot layer" of quantity on had per that specific lot number. THEN when the lot number is sold on an invoice it will appear with the customer invoice. What we are looking for is a list of the lot numbers associated with the quantity on hand from receiving. Many businesses need visibility of the lot numbers at the time of Sales Order creation. The lot numbers many times contain the expiration date of the product which is crucial to the sales order process. Can you tell me where the "lot layers" are stored in MethodCRM?
