A Data Vault access role assignment is optional. If you assign a Data Vault access role to an entity, access is restricted to all archived data from the entity, regardless of the project that includes the entity. Only users that have the Data Discovery role and the access role that is assigned to the entity can access the archived data from the corresponding entity.

If you view or create custom reports and dashboards, you must assign a Data Vault access role to each entity on which you want to base a report. Users that create or view a report must have the same role assignment as the entity on which the report is based.

A Data Vault access role assignment is optional for projects that have the Data Vault as the target connection. If you assign an access role to an archive or retirement project, access is restricted to data that is archived from the project. The assignment at the project level overrides the assignment at the entity level. If the project include entities that have role assignments, Data Discovery ignores the entity level assignment. Only users that have the Data Discovery role and the Data Vault access role that is assigned to the project can access the archived data.
