When a defined end-user or a group of end-users logs in to the user page in Talend DQ Portal, each of them logs in to a specific session tailored according to the roles an administrator assigns to them and the permission the administrator grants them. This will decide what menus they have access to in their sessions and what actions they can do at report or dashboard generation time.
The administrator must assign users or group of users specific role(s) in order to grant/forbid access to various parameters at report/dashboard generation time. Depending on the assigned role(s), user or group of users will have access to specific parameter values (LoV) when generating reports, dashboards, etc.
For more information on roles, see How to assign one or more roles to a user.
For more information on parameter values, see Parameter values.
