multimapping issue at NW BPM

Hi All,

While I am working on simple collect and split pattern under NW BPM (PI 7.31 SP14), I am getting issue at multimapping, when I test with source xml which is take from the test tab, it is failing with the below error at channel monitoring as below

Error: com.sap.aii.adapter.xi.routing.RoutingException: InterfaceDetermination did not yield any actual interface

source xml is show as below:

<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">

But by referring the other forums based on the above error, I removed the above xml from the source xml message and tested it and it was working fine as expected but when I check the result xmls it is not having the actual data, it contains only the xml tags.

Here I attached my multimapping screen shot:

Here is my BPM looks like:

Could you check what is actually went wrong?
