   We get error "Fill requires an attached datasource eCODAFAMILYDESC 11874" in the BE Tester, see screenshot https://i.imgur.com/Thui8yW.png
   
   The DESC tables in this BE are calculated and do not have a source buffer.
   
   What is the correct way to set NO-FILL ?
   
   The DataAccess contains the code below but we see that OnBeforeFill is not executed if the top table is not fetched.
   
       method override protected void DefineReadEvents ():
   
           this-object:SetDatasetCallback("BEFORE-FILL", "OnBeforeFill").
   
       end method.
   
       /**
        * Purpose: sets fill-mode to "NO-FILL" of the read-only temp-tables
        * @param   dsCODADOMAIN Dataset CODADOMAIN
        */
       method public void OnBeforeFill (input dataset dsCODADOMAIN):
   
           buffer eCODADOMAINDESC:fill-mode = "NO-FILL".
           buffer eCODAFAMILYDESC:fill-mode = "NO-FILL".
           buffer eCODASUBFAMILYDESC:fill-mode = "NO-FILL".
   
       end method.

   The easiest is to exclude those tables from the Tables argument of the FetchDataRequest argument passed to the Data Access object's FetchData method.
   
   But setting it to NO-FILL like you did there works too. 
   
   Or you create a BEFORE-FILL callback for those tables as suggested by the error message.

   Hi Mike,
   
   The DESC tables are calculated tables containing descriptions of referenced records.
   The client decides whether he interested in the descriptions or not. This is done using the Tables property
   excluding those tables is not an option. The AssignSmartRecordInformation also uses Tables to determine which of the calculated tables should be created.
   
   The problem I have with the Onbeforefill on a buffer is that it fires too much, once for each parent record, the dataset beforefill is ok but that does not fire if the top table is not requested.
   
   I tried overriding DatasetFill but found that there are 2 almost identical methods
   DatasetBufferFill and DatasetBufferFill, they only differ in the assert and error message.
   
   I'm currently leaning toward overidding both methods in the CceDataAccess
   
   /* In CODADataAccess */
       method protected override void BeforeFill(phDataset as handle, poFetchDataRequest as IFetchDataRequest):
   
           buffer eCODADOMAINDESC:fill-mode = "NO-FILL".
           buffer eCODAFAMILYDESC:fill-mode = "NO-FILL".
           buffer eCODASUBFAMILYDESC:fill-mode = "NO-FILL".
   
       end method.
   
   /* In CceDataAccess */
       method protected override void BeforeFill(phDataset as handle, poFetchDataRequest as IFetchDataRequest):
   
           buffer eCODADOMAINDESC:fill-mode = "NO-FILL".
           buffer eCODAFAMILYDESC:fill-mode = "NO-FILL".
           buffer eCODASUBFAMILYDESC:fill-mode = "NO-FILL".
   
       end method.
   
       method protected override logical DatasetFill(phDataset as handle, poFetchDataRequest as IFetchDataRequest):
           this-object:BeforeFill(phDataset, poFetchDataRequest).
           return super:DatasetFill(phDataset, poFetchDataRequest).
       end method.
   
       method protected override logical DatasetBufferFill(phDataset as handle, poFetchDataRequest as IFetchDataRequest):
   
           this-object:BeforeFill(phDataset, poFetchDataRequest).
           return super:DatasetBufferFill(phDataset, poFetchDataRequest).
   
       end method.

   A BEFORE-FILL callback on the Dataset?
