# Role Concept

## Manager Information

| In many cases, it can be useful to restrict the modification of a specific document to the members of a specific project group. The following examples require the EDB-DOC-UPD privilege (document master) or the EDB-DOC-3DM-UPD privilege (document type 3D_MODEL), etc. The access rule to be defined must verify that the object to be edited is assigned to a project whose list of positions (jobs) includes one that USER1 performs.
