Yes, the Project based access can be enabled (configurable). In this case, registration and access (to be viewed or to be modified) of compounds will be available only if the logged in user has the specified permission within the given project. For a logged in user, the available projects will be displayed in the field drop-down list. No registration will be possible using newly given Project name(s) as additional data. Otherwise, when Project based access is disabled, Project fields can be freely used as additional data, no filtering is made.

Note that regardless of the project settings, all the submissions that lack the Project info will be visible.
