Why a Group cannot be added to a role on a Vault document?
Override rules in the Lifecycle are preventing groups from being added to a role.
Check the override rules to ensure the group can be added.
- Navigate to: Admin --> Configuration --> Document Lifecycles --> [Document Lifecycle] --> Roles.
- Select the role in question.
- Navigate to the Override Rules tab.
The screen shows if there are any rules set in place to prevent a particular user or group from being added to a role on a document within the Lifecycle.
