Can you show what it should look like by the inventory sites? How can It notify me that if SKU ABC123 is in warehouse A and ABC123 is not in warehouse B, how can It notify me that warehouse B needs a refill from warehouse A?

2. Even if warehouse B is running low, how can it notify me for a refill? 

Can you please send a screenshot of how this works and what I need to make the site MIN and MAX?
