Dear MahGah,
Thanks for the info. This same item will be sold in 2 different scenario
1. Inventory sales via warehouse.
2. Drop shipment sales where we do not need to keep track the inventory. the item will be shipped from the supplier to the customer.
So we was wonder do we need to create 2 item code for each scenario or use one. if use one item code we will setup as type = inventory, and how to handle the sales order in the event of drop shipment when inventory is not involved
