Hi , Still a newbie for ensemble, I am trying to convert XML message to HL7 Message. I am using Custom schema for XML structure which includes MSH and PID segments from HL7 Message. These are the service, process, Operation classes i am using  Business service-EnsLib.EDI.XML.Service.FileService Business Process-EnsLib.MsgRouter.RoutingEngine Business operation -EnsLib.HL7.Operation.FileOperation I am using data transformation to convert XML message to HL7 message  and data transformation is working fine and im getting this in the business operation.
 
ERROR <Ens>ErrGeneral: Not routing to target(s) 'HL7Output' because of error in Transform 'CSTOM.TXML.XMLToHL7' : ERROR <Ens>ErrException: <PROPERTY DOES NOT EXIST>zTransform+7^CSTOM.TXML.XMLToHL7.1 *MSH,EnsLib.EDI.XML.Document -- logged as '-' number - @' Set tSC1=target.SetValueAt(source.MSH.EncodingCharacters,"MSH:EncodingCharacters","set","")'   Please let me know if i missed any thing in this process?   Thanks, Smythee
