To edit a group's role assignment:
In the left pane of the Process Administrator, click Groups.
From the group list , select a group Name.
On the Groups | Edit Group page, click Assigned Roles.
On the Groups | Edit Group | Assigned Roles page, select a Role ID.
On the Groups | Edit Group | Assigned Roles | Role Assignment page, edit the Parameter, Rank, and Permissions for the role.
Click Save.
Note: A participant will only be able to use assigned permissions if a process has been designed to include the activities that correspond to these permissions. In other words, a participant will be able to grab a work list item if they have the grab permission and their role has a grab activity in the process that was created in Process Designer.
