The supervisor gives the signed requisition to the secretary. The secretary enters the information on the requisition into the system. The information includes the Employee# of the employee who made the request and the Employee# of the supervisor. The system checks the Employee table to verify that both employees’ information is valid. The computer checks to determine that the order is to an approved supplier (supplier should be in the Supplier table). If the odder is for inventory, the system checks that an inventory record for the item already exists in the Inventory table. The system checks that the information entered is complete. It then records the information in the Requisition table
