Administering Access-Group Access Control

---

You associate an access group to a catalog or category of master data. When an access group is associated with a catalog or a category, the users associated with the access group have visibility of the data in the catalog or the category.

The following principles apply to access-group access control. An access group in the following context is an individual node in an access group hierarchy:

Private catalogs and categories. A catalog is a hierarchy of categories. A catalog cannot itself contain data. To apply access-group access control on all of a catalog's categories, you must designate the catalog as private, and then associate access groups to the catalog. If a catalog is not private, then any user can see data in its categories. You can designate individual categories private within a public catalog.
Access group access is inherited. If an access group is associated with a category, then the group's descendant groups (child, grandchild, and so on) are automatically associated with the category. Conversely, if an access group is disassociated with a category, then its descendant groups are also disassociated. The inheritance association is enforced at run time.
Cascading category visibility is optional.
If an access group is associated with a category, the Cascade button provides that the access group is automatically associated with that category's descendant categories (child, grandchild, and so on). Therefore, users associated with the access group have access to the data in those descendant categories.
If the access group is disassociated with the category, then the access group is automatically disassociated with that category's descendant categories. If the access group is disassociated with one of the descendant categories, then the access group's cascading visibility is granted only down to, but not including, that descendant category.
Once the Cascade button is set, cascading access can only be disabled by disassociating the access group from a category. The flag itself cannot be unset.
If the Cascade button is not used, access is limited to the individual category to which the access group is associated.
