Setting Permissions through the Access Table
Through the ad hoc access rules generated from the use of the Access table on the Edit Access Control window, users can grant permissions on specific objects.
The list of permissions displayed in the Access table is determined by the following preferences that are under the Security category of the Preference Management utility:
The Access Permission Configuration (PDM) preference establishes the permissions that are displayed and which permissions can be edited when the Access table is launched from within a product or library context. By default, this preference is locked at the site level and can be viewed from the organization, product, and library levels. To set this preference at a different level, unlock the site-level preference.
* 
The default settings for the Access Permission Configuration (PDM) preference do not allow users to update any permissions; users can only view a subset of the permissions. Using this default means that if users select multiple objects and then attempt to use the Edit Access Control action, they will see a message saying there are no permissions that they can change.
The Access Permission Configuration preference establishes the permissions that are displayed and which permissions can be edited when the Access table is launched from all contexts except a product or library context. By default, this preference can be set by administrators of the site, organization, project, or program contexts.
