Automapper not mapping ID property of compose object when object is null

Question

I am using Automapper 6.2.2.0, which I think is the latest, in my web project (ASP.NET WebForms) and also in my Business layer, here is what Automapper is not mapping and don't know why:

Here is the relationship in the database, also exist the corresponding Business Objects and the Model of the Database (using LINQ to SQL)

this is the Automapper profile:

public class ServicePlanProfile: Profile
{
    public ServicePlanProfile()
    {
        //ProcedureCodeUnits
        CreateMap<ExtendedProcedureCodeUnit, ProcedureCodeUnit>().ReverseMap();

        CreateMap<ExtendedProcedureCode, ProcedureCode>().ReverseMap();

        CreateMap<ExtendedServiceCategory, ServiceCategory>().ReverseMap();

        CreateMap<ExtendedServiceSubCategory, ServiceSubCategory>().ReverseMap();
    }
}

have this code in the Global.asax file to kick off the Automapper configurations:

//Automapper configuration
    Mapper.Initialize(
        cfg=>
        {
            cfg.AddProfile<AutoMapperProfile>();
            cfg.AddProfile<ServicePlanProfile>();
            cfg.AddProfile<IncidentTrackingProfile>();
        }
    );

And here, following the steps in the Automapper docs, is the expression tree generated

Don't know why Automapper is not mapping ServiceCategoryID and ServiceSubCategoryID fields, any clue?

I did not it was possible to access the generated expression in automapper — Hasan Emrah Süngü, Apr 14 '18 at 04:58
In order to get the right execution plan you have to use the configuration you use for mapping. That's Mapper.Configuration in your case. — Lucian Bargaoanu, Apr 14 '18 at 08:12
@LucianBargaoanu how is it possible to get the generated expression trees — Hasan Emrah Süngü, Apr 14 '18 at 08:43

@LucianBargaoanu I use Mapper.Configuration as you suggested but still the same. I did this: `CreateMap() .ForMember(dest=>dest.ServiceCategory, opt=>opt.Ignore()) .ForMember(dest=>dest.ServiceSubCategory, opt=>opt.Ignore()) .ReverseMap();` and now is mapping the correct values. Any idea why? — ddieppa, Apr 16 '18 at 11:45
Probably [this](http://automapperdocs.readthedocs.io/en/latest/Reverse-Mapping-and-Unflattening.html). — Lucian Bargaoanu, Apr 16 '18 at 12:11
