@Eduard Lebedyuk I have tried changing the file to a txt file and the file is being created with nothing in it

@Eduard Lebedyuk Looked at the class this classEnsLib.RecordMap.Service.BatchFileService and the EnsLib.RecordMap.Service.BatchStandard class apparently these are fine  but for some reason the custom class acts as if it goes into a loop.I have put some traces in my code and tried to capture the status and change  it to fail if a certain validation fails but that makes the whole service to log an error after successfully delivering the first message .

here are the changes made thanks for your help

ClassMethod GetBatchHeader(pIOStream As %IO.DeviceStream, pTimeout As %Numeric = -1, Output pBatch As EnsLib.RecordMap.SimpleBatch, ByRef pLookAhead As %String) As %Status

     }
 Catch ex
    {
      $$$TRACE("in catch]")
    Set tStatus = $$$EnsSystemError
      quit
      }
      
 Quit tStatus
}

Since this is made up of three classes how do I control the status to send the call with within the block have a look at where  I have newStatus and I would like to quit and pass new status

@Eduard Lebedyuk

yes that the expected results even if you can not move the last two elements to be last just making something similar might help

Thanks for the advice have changed my code but come to a problem while reading my stream as there seems to an error with the XSLT XML Transformer Error: SAXParseException  I do not seems to see what the problem is as I tested my XLT with the XLT Transform Wizard and it all worked fine could you please have a look at the xml and the XLT and see if you can spot where I am going wrong thanks in advance
