[ABAP Mapping] No output

Question

Hey,
try to do a scenario like "How to use ABAP mapping in SAP XI 3.0", but got no output.
Is it correct that we don't need a namespace for abap mapping? In the "How to" document the namespace field is empty, but in sxmb_moni he says:
<b>  <SAP:AdditionalText>com.sap.aii.af.ra.ms.api.DeliveryException: error while processing the request to rfc-client: com.sap.aii.af.rfc.afcommunication.RfcAFWException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: could not get functionname from XML requst: com.sap.aii.af.rfc.RfcAdapterException: failed to read funtionname from XML document: missing namespace declaration(2)</SAP:AdditionalText> </b>
But he takes the ABAP mapping, because in ABAP code I create following trace node:
<i>  DATA: l_trace TYPE string.
  CONCATENATE 'Chris Sender Service = ' l_sender_service INTO l_trace.
  trace->trace( level = '1'
  message = l_trace ).</i>
And in sxmb_moni he got it:
<i><Trace level="1" type="T">Chris Sender Service =BS_Reisebuero2</Trace> </i>
In sxi_mapping_test he writes, that the mapping was successful, but didn't create the output structure. Do I have a wrong ABAP code? Could it be, that I have a wrong append_child??
Here it is (it equals the how to):

Hi,
I took a working scenario, that is runnable with java- and graphical mapping.
Just change it to ABAP-Mapping.
I just had forget to include the namespace into abap mapping. So the output has to look like:
<ns1:SXIDEMO_AIRL_FLIGHT_CHECKAVAIL <b>xmlns:ns1="urn:sap-com:document:sap:rfc:functions"</b>>
That was the missing namespace. Another problem was my created structure. I used the function append_child with a wrong input.
Your tip, that I'm able to use the debugger in
sxi_mapping test was great. So points for you!
