Hello, your reply looks as though you didn't read my question.

I don't need an explanation of why purchase orders are useful, I know what purchase orders are and how to use them.

My request was:

I need help understanding Warehouse Manager and the Purchase Order fulfillment and management worksheets in QB Desktop. 

...we need more control in the warehouse - notification of items received, notes on order issues, etc.

I would like to UNDERSTAND HOW THEY (Warehouse Manager, Purchase Order Fulfillment and Purchase Order Management) ALL WORK TOGETHER and how best our company can utilize them.

I would like to be contacted by someone who understands these functionalities and how they interrelate. 

I DON'T need general articles that tell you what to select in Preferences. Not helpful.
