Draw a Level 1 and a Level 2 Data Flow Diagram

Your staff consists of three purchasing agents plus yourself. Your department receives purchase orders (PO) from other departments in the company. The agents check the PO. for completeness and accuracy, and they then check the corporate budget to determine if sufficient funds exist. If the funds exist, the agents choose, from departmental records, the appropriate vendors; and then they order the items. When items are received in Shipping, the shipping personnel generate a Receipt document and send a copy of that document to your department. When all items have been received, the agent closes the PO. Periodically, you review an open PO to ensure that the work is being completed on time. Generate a dataflovw. diagram for this department.
