Overlapping User and Group Permissions (Master Data Services)
A user's permissions are based on:
Permissions from group memberships.
Permissions assigned explicitly to the user.
If a user is a member of multiple groups, and those groups have access to Master Data Manager, the following rules apply:
Deny overrides all other permissions.
Update overrides Read-only.
These rules apply to both the Models and Hierarchy Members tabs. Permissions are resolved for each tab and then combined. For more information, see How Permissions Are Determined (Master Data Services).
You can view the resolution of user and group overlapping permissions in the user interface. Both the Models and Hierarchy Members tab have a drop-down list from which you can choose Effective to view effective permissions.
The user belongs to Group 1 and Group 2.
The user has Update permission to a group of members in a hierarchy node.
Group 1 has Read-only permission to a group of members in a hierarchy node.
Group 2 has Read-only permission to a group of members in a hierarchy node.
Result: The user's effective permission is Update to the members.
