How to handle Changes in the Structure of Outbound Message.

Question

Hi Experts,
I have a File2RFC scenario where the Outbound Message fields are (for e.g,) ID,Name,Loc, and Status. The structure of the xml file which needs to be picked by sender file adapter is changing each time based on the data entered by the user. I am sure this will fail in IS with RuntimeException in Message-Mapping transformation Error. Is there anyway to handle this kind of situation.
Message Sample- 1 (Message Processed successfully as it contains all the 4 fields...)
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Send xmlns:ns0="http://File2File">
   <root>
      <ID>1234</VesselID>
      <Name>PIUSER</VesselName>
      <Loc>System A</Type>
      <Status>1</Status>
   </root>
</ns0:MT_Send>
Message Sample-  2 (Message Failed with Runtime Mapping Exception in IS...'Loc' is missing)
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Send xmlns:ns0="http://File2File">
   <root>
      <ID>5678</VesselID>
      <Name>SAPUSER</VesselName>
      <Status>2</Status>
   </root>
</ns0:MT_Send>

Hi Ravi,
Thanks for the reply. I think changing the cardinality will not solve this issue. Because the file which is being picked by Sender file Adapter is changing its structure everytime based upon the values entired by the user.
For example - In Message 1 User has entered all the 4 values...so the structure is full.
Message Sample- 1 (Message Processed successfully as it contains all the 4 fields...)
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Send xmlns:ns0="http://File2File">
<root>
<ID>1234</VesselID>
<Name>PIUSER</VesselName>
<Loc>System A</Type>
<Status>1</Status>
</root>
</ns0:MT_Send>
In Message 2 - user has entered only 3 values...Though I have kept Loc as 0 to Unbound it fails as there is no tag <LOC></Loc> here.
Message Sample- 2 (Message Failed with Runtime Mapping Exception in IS...'Loc' Tag is missing)
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Send xmlns:ns0="http://File2File">
<root>
<ID>5678</VesselID>
<Name>SAPUSER</VesselName>
<Status>2</Status>
</root>
</ns0:MT_Send>
