For a friend I want to make an inventory for products that are already in his warehouse. As the warehouse works with stock movements, I'm a bit puzzled on how to "move" products to the locations they're already in. Business is a vintage aircraft restoration company, so lot of the parts are taken from other aircraft and kept as spare parts for restoration projects. They're stored in the warehouse at a specific location.
What would be the flow that I have to follow in order to have them in the current stock?
