answer the following questions:

1. Computer system input screens and routines are used to generate purchase order documents/transactions (The Purchasing Module of an ERP). Identify several types of controls you would design into these screens to help ensure only accurate and authorized data is input into the system and processed when creating a new purchase order. Be creative!
2. If you were going to design a Purchase Order System "Exception" report, what types of "exceptions" related to the Purchase Order Process would you include? I am not looking for ALL exceptions, just a few.
3. Scenario: The warehouse manager greets a delivery truck at the warehouse dock. The driver is delivering an order from ABC vendor that included 53 pairs of bookends. The warehouse managers computer screen says that the order should have only been for 35 pair of bookends. The driver says to the warehouse manager "I'll just leave them here on the dock, you can return them if the order was not right". What should the warehouse manager do?
