Administering Access Groups
You can group parties of types Position, Organization, Household, and User List into access groups for the purpose of controlling their individual members’ access to data.
You administer access groups in the Administration - Group screen. This screen contains the Access Groups tree and the Access Groups list.
The Access Groups tree lists all access groups on the second level of the tree. Each access group can be expanded to show its descendants. Therefore, an access group can appear at different levels in multiple branches of the tree. An access group that has no parent access group is the highest node of an access group hierarchy. For information about access groups, see Access Control for Parties and About Access-Group Access Control.
