Message Mapping via Test tab

Question

Hi All
I am trying to send a message via the Test tab of the integration server.I have entered all the details like sender and receiver service and sender interface and namespace. The scenario is JDBC to file. I am using EO as qualilty of effort .The scenario is asynchronous .Once i test the payload in message mapping it gives me the correct output values. But when the same payload I paste it and send via the test tab it does not go thru. I mean sometimes I get the same message at both sender and receiver.And other times it goes into error "Split mapping created no messages " .Can anyone please help me on this as to what might be the problem.
We have used enhanced interface determination in this.Is it due to this????
The payload appears like this.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
   <ns0:Message1>
      <ns1:MT_TEST xmlns:ns1="http://testinterface.com">
         <row>
            <DESCRIPTION/>
            <ITEM_NAME/>
            <CREATION_DATE/>
         </row>
      </ns1:MT_TEST>
   </ns0:Message1>
</ns0:Messages>

<?xml version="1.0" encoding="UTF-8"?>
<ns1:MT_TEST xmlns:ns1="http://testinterface.com">
<row>
<DESCRIPTION/>
<ITEM_NAME/>
<CREATION_DATE/>
</row>
</ns1:MT_TEST>
Only send the above structure as payload....do not include the other tags....they cause the error
