Entity framework saving context

问题

public static TraffickingToScheduled CreateTraffickingToScheduled(int ScheduledID, global::System.DateTime startDate, global::System.DateTime endDate, int originatingNetworkID, int showID, int seasonID, int episodeID, string ffDisable)
{
    TraffickingToScheduled traffickingToScheduled = new TraffickingToScheduled();
    traffickingToScheduled.ScheduledID = ScheduledID;
    traffickingToScheduled.StartDate = startDate;
    traffickingToScheduled.EndDate = endDate;
    traffickingToScheduled.OriginatingNetworkID = originatingNetworkID;
    traffickingToScheduled.ShowID = showID;
    traffickingToScheduled.SeasonID = seasonID;
    traffickingToScheduled.EpisodeID = episodeID;
    traffickingToScheduled.FFDisable = ffDisable;
    return traffickingToScheduled;
}
Context.AddToTraffickingToScheduleds(traffickingToScheduled);
Save();

I have a foreign reference with Scheduled table to TraffickingToScheduled table with 1 to 1 relationship. while saving it throws the error as TraffickingToScheduled participate in TraffickingToScheduled_FK_Scheduled relationship. 0 related "Scheduled" is found.1 Scheduled is expected.
