The idea is to have a property in the Parent BO to the ChildBO and in this ChildBO to another Child like this: CustomersBO.OrdersBO.OrderItemsBO.ItemPrice How can I do that for SF Business Object?

For strings, that is Nothing (null), hence the error. Don't forget the other part of the code, which is to set values of that new row: _insuranceCompany.InsuranceCompanyName = String.Empty ...etc. Do this right after you call NewRow()

When using BO.NewRow() SF will populate it with the default values which are good enough in my case. In order to make it work I added a "New" command to initialize the Private BO variable like this: Private _insuranceCompany As New InsuranceCompanyBO Then I made some changes to the property code to make sure the BO is filled all the time, like this: Public ReadOnly Property [InsuranceCompany]() As InsuranceCompanyBO Get '-- If the private BO has not been created, then create it here. If _insuranceCompany Is Nothing Then Dim _insuranceCompany As New InsuranceCompanyBO End If If Not String.IsNullOrEmpty(Me.FK_InsuranceCompany) Then _insuranceCompany.FillByPrimaryKey(Me.FK_InsuranceCompany) End If '-- Check if the BO is empty... '-- Initiailize a new row, default values could be added here if needed. If _insuranceCompany.Count = 0 Then _insuranceCompany.NewRow() '-- AcceptChanges on the table, so it isn't dirty (but doesn't save anything to the database) _insuranceCompany.CurrentDataTable.AcceptChanges() End If Return _insuranceCompany End Get End Property So far the code above is working fine.
