Out-of-date
Objects that are out-of-date are read-only and cannot be opened for editing in the ContentRoutingProject or standard Project and cannot be posted.
Out-of-date objects are those whose revision number under the configuration object (that is, outside the ContentRoutingProject or Project) is more recent (later) than the revision number of the object in the ContentRoutingProject or Project. Objects in your ContentRoutingProject or standard Project become out-of-date when the objects are posted back to the configuration from another ContentRoutingProject or Project.
