   I have a dataset model class that I am using to update a group of records.
   
   It has two two tables PhysicalInv and PhyLine. The PhysicalInv is the parent with the PhyLine the child (one to many).
   
   I am using the code below to fetch the one PhysicalInv record and all of the PhyLine records.
   
   oPhysicalInv = NEW Osprey.Pos.PhysicalInv.PhysicalInvDatasetModel ().
   // set filters
   oPhysicalInv:PhysicalInv:Filter:RunNum:EQ(poParam:RunNum). // The RunNum we are posting
   oPhysicalInv:PhysicalInv:FillPhyLine = TRUE. 
   // oPhysicalInv:PhysicalInv:FillChildTables = "ePhyLine":U. // we want ALL PhyLine records as well 
   
   oPhysicalInv:BatchSize = 0. // we want ALL records not just default of 100
   oPhysicalInv:PhysicalInv:Fill().
   
   I am then looping through the PhyLine records, updating them and then calling Savechanges. If Savechanges fails (validation, etc.) is there a way to Cancel the changes for this one record? I want to log the error and continue processing the remaining records. 
   
   DO WHILE oPhysicalInv:PhyLine:Available:
   
       // code that updates PhyLine record
       poPhysicalInv:SaveChanges().
       // save changes
       oPhysicalInv:PhyLine:GetNext(). 
   
   END.

   If I understand your demand correctly, you should be able to call
   
   poPhysicalInv:BufferHandle:REJECT-ROW-CHANGES () .
