Silver Inventory System

Question: How do I go in to inventory control and modify the "on hold", "allocated", and "available" of each product?

When you create receiving list you increase amount of the arrived product.When you create invoice you increase amount of sold product. The "on hold" is equal arrived minus sold. When you create sale order you increase "allocated" amount of product. The "available" amount is "on hold" minus "allocated"
