I want to use my database in a Pawn shop and Second hand shop, so we lent money on an item and then that item get a pawn number like "P000001" then when they do not pay that item it must go on the stock list and then get a Product number like "S000001". And then their is Lay-buy.  When a customer lay-buy a product, that product get a Lay-buy number like L000001. If possible can you include some similar in your asset tracking seminar
