When you enable an item in a functional area, the item is assigned to the default (mandatory) category set and default category of the functional area. You can override the category set’s default category. In addition, you can manually assign your item to an unlimited number of category sets. You may optionally assign an item to more than one category within a category set based on the category set definition.
When you assign your item to another organization Oracle Inventory copies Master level category sets, Organization level default category sets, and the associated categories assigned in the Item Master organization. This means that if you manually assign an Organization level category set to the item in the Master organization, Inventory does not copy over that Organization level category set when you assign that item to another organization.
After assigning an item to another organization you can disable the item for one or more functional areas in the new organization. However, Inventory does not remove the corresponding functional area’s default category set. For example, you may have set the value of the Purchased attribute to ”Yes” when you defined the item in the item master organization. When you assign this item to another organization Inventory copies over the ”Yes” value of the Purchased attribute and
therefore assigns the default category set of the purchasing functional area. In the new organization you may decide to set the value of the Purchased attribute to ”No.” After you disable the item for the purchasing functional area in the new organization, the item still retains the purchasing default category set. You may manually delete the purchasing category set in the new organization.
If you copy an item from another item with category sets defined at the Organization level, Inventory assigns the new item the default categories of the mandatory category sets, even if the original item did not have the default categories. This is because Inventory copies the values of the item defining attributes and not the category sets and categories themselves.
