   In the code below if I do not use the GetFirst on the DatasetModel class my first record will appear twice in my loop. Should I need to do this? It does work but I was not expecting to have to use GetFirst before my loop.
   
   DEFINE VARIABLE oRebateCustomer  AS Osprey.Pos.RebateCustomer.RebateCustomerDatasetModel  NO-UNDO.
   
   
   oRebateCustomer = NEW Osprey.Pos.RebateCustomer.RebateCustomerDatasetModel ().
   oRebateCustomer:RetrieveData("eRebateCustomer,eEcoupon",
                                                 "FOR EACH eRebateCustomer WHERE eRebateCustomer.CustomerNum = 244001" + CHR(1) +
                                                 "FOR EACH eEcoupon WHERE eEcoupon.IsUsed = TRUE"
                                ).
                               
   oRebateCustomer:UseDatasetQueries().
   /* Roger Blanchard / Osprey Retail Systems Sep 18, 2019
    If I do not use GetFirst then the first record will be duplicated
    in my loop below
   */
   oRebateCustomer:RebateCustomer:GetFirst().
   DO WHILE oRebateCustomer:RebateCustomer:Available:
    
    MESSAGE
     "oRebateCustomer:RebateCustomer:CustomerNum=" oRebateCustomer:RebateCustomer:CustomerNum  SKIP
     "oRebateCustomer:RebateCustomer:RebateId=" oRebateCustomer:RebateCustomer:RebateId  SKIP
    VIEW-AS ALERT-BOX.
   
    oRebateCustomer:RebateCustomer:GetNext(). 
    
   END.    
   FINALLY:
    DELETE OBJECT oRebateCustomer NO-ERROR.    
   END FINALLY.
