IHC Purchasing Department orders all types of inventory items for their 100 health club locations: 1) Fitness machines 2) Weight machines and equipment 3) Maintenance and repair items 4) Computers and other IT equipment 5) Sports equipment Each item that IHC orders is assigned one of the above item type categories. Each purchasing agent in the system is assigned at least one of the above item type categories; meaning that each agent can only place orders for items within their assigned category(s). Each item type category is assigned more than one purchasing agent. This restriction is enforced by the system. Purchase Agents must login to use the system. Purchase Orders must contain at least one item from the inventory master but a PO does not have to contain items from the same item type category. Each item is assigned at least one specific vendor in the system that it can be purchased from along with a current standard purchase price for the item from that vendor. Often, a vendor will be approved to provide IHC with many different items and many items can be provided by different vendors. The items appropriate current standard purchase price is used as the Actual Purchase Price for each item on the PO. Each PO must specify 1 vendor from the Vendor master from which all of the items will be ordered. The system calculates a Total Regular $ Amount for the PO by using the quantity ordered and actual purchase price for each line item on the PO. Purchasing agents are required to disclose conflicts of interest that they may have with specific vendors and this information is stored in the AIS system. Purchase Agents are not to create purchase orders for those vendors in which they have a conflict of interest and this policy is enforced by the system. Some agents have no restrictions and others may have many vendor restrictions. Most vendors have no restrictions but some have multiple. Activity Diagram: Create PO
