   I am trying to use the DatasetModelMode of Disconnected. I have created a BE defined with TT that are not bound to the DB. I want to use the DatasetModel class on the client to create TT records. I then want to call Savechanges where I will OVERRIDE the default handling to save the dataset on the client.
   
   The following code seems to create TT records. However, after the final create if I try to loop through the records there are none. Do I need to call Savechanges for each TT record being created? I did try that and get errors.
   
   I must be missing something. I did review SCL-1768 and updated my datasetmodel.template and then recreated my dataset model class.
   
   DEFINE VARIABLE oEJournal  AS Osprey.PointOfSale.EJournal.EJournalDatasetModel  NO-UNDO.
   
   oEJournal = NEW Osprey.PointOfSale.EJournal.EJournalDatasetModel (DatasetModelModeEnum:Disconnected). // disconnected mode
   
   oEJournal:EJournal:Create().
   oEJournal:EJournal:RecNum  = 1.
   oEJournal:EJournal:RecType = "98".

   oEJournal:EJournal:RecType = "1".

   Hi Roger,
   
   try calling 
   
   oEJournal:EJournal:QueryOpen().  
   
   before 
   
   oEJournal:EJournal:GetFirst().

   Mike,
   
   That did not work either. So, I went back and tried generating the classes again under the Generate tab. I noticed that these classes were generated in the backend project instead of shared. I think the wrong code was being used.
   
   If I first "Generate" under the Business entity tab the TT/DS include files are generated in the shared project. If I then "Generate classes" under the "Generate" tab the classes are then created in the shared project. Once I did that these new generated classes do seem to work.
   
   Thanks.
