Flow Chart: I need help making a flow chart for the following process:

Purchasing

Every Friday afternoon, the salespeople prepare weekly sales reports from their copies of the sales orders. They send the reports to Ed and then refile their sales orders by customer name. Ed reviews the weekly sales reports and the weekly inventory reports prepared by Fred and Ted. Ed "eyeballs" the numbers, notes any shortages in inventory, and prepares 3-part purchase orders. He mails the original to the vendor, sends one to the twins in the distribution center and one copy to Mary.

As noted above, Fred and Ted have a card file for keeping track of inventory. Each card has a running balance to expedite the preparation of the weekly inventory reports for Ed. When they receive a copy of a purchase order, they pull the cards for the item(s) ordered, record the quantity ordered and the P.O. number, and file the purchase order in numerical order. When the shipment arrives, Fred and Ted pulls the purchase order to make sure that the items received were the items ordered and note any back orders on the purchase order. Then they pull the inventory cards, mark the items received, and prepare a receiving report that is sent to Mary.

Thanks in advance!
