The purpose of Purchases is to increase your stock levels by inputting into the system the orders you made to your suppliers.
This is what happens when you create a new purchase or modify or delete an existing purchase:
the Stock levels of products are recalculated
the Average Cost for products is recalculated
the Last Cost for products is updated
