ABAP Proxy error

Question

Dear Friends,
I am facing a problem when i use a ABAP client proxy (asynchronously)
An error is raised during proxy method call-
<CODE>SERIALIZE_APPLICATION_DATA</CODE>
<b>  <ERRORTEXT>Conversion error ABAP => XML (Request Message; error ID: CX_ST_INVALID_XML;
(/1SAI/TAS00000000000000000005 XML Bytepos.: 0 XML Path:
Error Text: Executing the operation '&OPERATION&' leads to an invalid XML document) )</ERRORTEXT></b>
The same proxy runs fine in upstream system (dev) but doesnot run in downstream system (QA) even though all proxy objects have been transferred.
This proxy & another proxy from the same calling report program  is serialized in a queue.The first proxy is raising this error, but the second proxy call is successful.
Can someone help,
Thanks

Hi Guru,
All the fields in the data type have string - also this roxy works fine in devpt. system- but it doesnt work in downstream QA system.
Other proxy interfaces in the QA system work fine.
The error message when i single test the proxy is as follows-
- <CX_XMS_SYSTEM_ERROR>
  <ID>SERIALIZE_APPLICATION_DATA</ID>
  <P1>Request Message</P1>
  <P2>CX_ST_INVALID_XML</P2>
  <P3>/1SAI/TAS00000000000000000005</P3>
  <P4>XML Bytepos.: 0 XML Path: Error Text: Executing the operation '&OPERATION&' leads to an invalid XML document</P4>
  <INFO />
  <CATEGORY>XIProxy</CATEGORY>
  <AREA>ABAP</AREA>
<CX_ST_ERROR>
  <ST_PROGNAME>/1SAI/TAS00000000000000000005</ST_PROGNAME>

  <X-ML_PATH />
  <ST_IC>2</ST_IC>
  <ST_TIMESTAMP>20070907163313</ST_TIMESTAMP>
  </CX_ST_ERROR>
Any other possible solutions ?
