   I have a pretty simple maintenance form. It has a toolbar, smartbusinessentityadapter and a smartviewer.
   
   The smartviewer is setup with a barcode scanner for quick retrieval of a record from the server. I am using the method below to retrieve the one record from the backend. This code works just fine as I can scan (or key enter) and retrieve the item just fine. However, as soon as I update a record or create a new record the RetrieveData no longer works. The property THIS-OBJECT:PoLineAdapter:Available = false even though in the BE:ReceiveData I can see the values of the TT just fine. 
   
   Do I need to RESET something on the frontend?
   
   Any help would be appreciated...
   
   
   METHOD PRIVATE VOID FetchPoLine(  ):
     
     DEFINE VARIABLE cWhereString AS CHARACTER       NO-UNDO. 
     DEFINE VARIABLE oRequest   AS Consultingwerk.OERA.FetchDataRequest NO-UNDO.
     DEFINE VARIABLE lOkay   AS LOGICAL         NO-UNDO.
     
     cWhereString = "WHERE ePoLine.OrderNum = " + STRING (THIS-OBJECT:OrderNum) + " AND ePoLine.SeqNum = " + STRING (THIS-OBJECT:SeqNum) + " AND ePoLine.ItemNum = " + QUOTER (cCurrentItemNum) + " AND ePoLine.PackNum = " + STRING (iCurrentPackNum).
     
   // Tried adding this to solve the issue with retrieving after updating a record
     THIS-OBJECT:PoLineAdapter:ClearPreviousQueryString(TRUE).
     
     THIS-OBJECT:PoLineAdapter:EmptyDatasetOnRetrieveData = TRUE.
     THIS-OBJECT:PoLineAdapter:BatchSize = 1.  // only want one record
     THIS-OBJECT:PoLineAdapter:QueryString = "FOR EACH ePoLine " + cWhereString. 
     THIS-OBJECT:PoLineAdapter:RetrieveData().
     
     IF NOT THIS-OBJECT:PoLineAdapter:Available THEN
     DO:
      THIS-OBJECT:AddRecord().
     END.
     
     ELSE
     DO:
      THIS-OBJECT:EnableFields(EnableFieldsEnum:Update).
       END.
     
     RETURN.
    END METHOD.

   Just that I understand this ... the FetchPoLine method is called whenever a bar code is scanned? And THIS-OBJECT:OrderNum, THIS-OBJECT:SeqNum, cCurrentItemNum and iCurrnetPackNum are values resulting from scanning the bar code? 
   
   I doubt that this is relevant for this case - but I would try to avoid using global variables for that purpose. I'd pass actual parameters to the method. But that's another story.
   
   There is nothing required to reset the SmartBusinessEntityAdapter. So you're sure that on the second run, you're producing a valid query string? Did you verify the value of
   
     THIS-OBJECT:PoLineAdapter:QueryString 
   
   After calling the 
   
    THIS-OBJECT:PoLineAdapter:RetrieveData().
   
   can you try to
   
   MESSAGE
       BufferHelper:NumRecords (THIS-OBJECT:PoLineAdapter:QueryHandle:GET-BUFFER-HANDLE (1)) SKIP 
       THIS-OBJECT:PoLineAdapter:BindingSource:Count
   VIEW AS ALERT-BOX

   "the FetchPoLine method is called whenever a bar code is scanned"
   
   The sequence is;
   1. We need to validate the barcode that was just scanned. We do this by using InvokeMethod on our ItemBusinessEntity and pass the scanned barcode. The GetItem method on the BE will return back our unique ItemNum. 
   
   oItemParameter = NEW Osprey.Pos.Item.ItemParameter ().
        
   oItemParameter:UpcNum  = cUpcNum. // this is the barcode that was scanned 
   oItemParameter:PackNum = iPackNum.
       
   FrameworkSettings:ServiceAdapter:InvokeMethod ("Default",
                                                                              "Osprey.Pos.Item.ItemBusinessEntity",
                                                                              "GetItem",
                                                                              INPUT-OUTPUT DATASET-HANDLE hDSet,
                                                                               oItemParameter).
   
   2. If we get a valid ItemNum returned we then use the RetrieveData of the Adapter.
   
   cWhereString = "WHERE eBatchItem.BatchId = " + STRING (THIS-OBJECT:BatchId) + " AND eBatchItem.ItemNum = " + QUOTER (cCurrentItemNum) + " AND eBatchItem.PackNum = " + STRING (iCurrentPackNum).
     
     THIS-OBJECT:BatchItemAdapter:EmptyDatasetOnRetrieveData = TRUE.
     THIS-OBJECT:BatchItemAdapter:BatchSize = 1.  // only want one record
     THIS-OBJECT:BatchItemAdapter:QueryString = "FOR EACH eBatchItem " + cWhereString. 
     THIS-OBJECT:BatchItemAdapter:RetrieveData().
   
   I did check the QueryString and it looked correct. As I said if I add logic to RetrieveData in the BE to display the TT record it is correct.
   
   I will try the following;
   
   MESSAGE
       BufferHelper:NumRecords (THIS-OBJECT:PoLineAdapter:QueryHandle:GET-BUFFER-HANDLE (1)) SKIP 
       THIS-OBJECT:PoLineAdapter:BindingSource:Count
   VIEW AS ALERT-BOX

   The results were;
   
   BufferHelper:NumRecords (THIS-OBJECT:PoLineAdapter:QueryHandle:GET-BUFFER-HANDLE (1)) = 1
   THIS-OBJECT:PoLineAdapter:BindingSource:Count = 0

   I tried adding 
   
   THIS-OBJECT:PoLineAdapter:BindingSource:RefreshAll().
   
   made no difference.

   Then you should invoke the ....:QueryHandle:QUERY-OPEN() method.
   
   But I don't see why that should be required. Is there an error thrown somewhere? Maybe in the default-window of the ABL session? Or anything in the AppServer log?

   I will check again but I did not see any errors.
   
   Let me try what you suggest to see if it solves the issues and then will look at logs.

   Adding the QUERY-OPEN on the Adapter:QueryHandle did not help.
   
   No errors on Appserver logs just a warning. It looks like it found the record just fine.
   
   I also looked at client logs and no errors.

    We'll continue to investigate this in the support desk ticket created for the case.
    
    We may have to create a repro for this.
