By assigning access to a form, you control which users can change its design (for example, its layout and instructions) and input data. Users can select only members to which they have read or write access. Users can edit forms only if they have access to at least one member of each secured dimension. For example, if users have read-only access to the Europe entity, the rows and columns on forms that include the Europe entity are displayed as read-only. Users can change data only for members to which they have write access.
