After you set up the product lines and current cost method, you can define more specific information about each item.

Item information must be entered for every item you use or produce. Item Master Data defaults to all sites in an entity. Later in the course, you will learn that many attributes of an item can be different at each site.

Every item is identified by an item number. This item number is the same for all sites, as is some of the other identifying information, such as product line, unit of measure, and group and type.

In Item Master Maintenance (1.4.1), you enter inventory data, planning data, and cost data. The slide shows the basic information recorded in each of these areas.

You can also use separate functions to add or maintain item data, inventory data, planning data, and cost data. This lets different functional areas such as production planning and cost accounting have update access to their data only.
