File Conversion in Rec File Adapter with subnodes

Question

Hi
My XML Structure is like this -->
<?xml version="1.0" encoding="UTF-8" ?>
- <ns0:MT_Test xmlns:ns0="urn:TESTconversion">
  <MstName>Hello</MstName>
- <Header>
  <TableName>1tst</TableName>
  <PayDate>0102</PayDate>
  <TotalAmt>24.00</TotalAmt>
  <Total>000002</Total>
  <PaySource>CHK</PaySource>
- <Subheader>
  <TableName>1tst</TableName>
  <SelectCatgry>test</SelectCatgry>
  <CustID>200</CustID>
  <PayAmount>11.00</PayAmount>
  </Subheader>
- <Subheader>
  <TableName>1tst</TableName>
  <SelectCatgry>test</SelectCatgry>
  <CustID>400</CustID>
  <PayAmount>13.00</PayAmount>
  </Subheader>
  </Header>
- <Header>
  <TableName>1tst</TableName>
  <PayDate>0103</PayDate>
  <TotalAmt>10.00</TotalAmt>
  <Total>000001</Total>
  <PaySource>ONE</PaySource>
- <Subheader>
  <TableName>1tst</TableName>
  <SelectCatgry>test</SelectCatgry>
  <CustID>100</CustID>
  <PayAmount>10.00</PayAmount>
  </Subheader>
  </Header>
</ns0:MT_Test>
which means
MT_Test is root 1..1
Header is the sub-node of MT_test as 1...*
Subheader is sub-node of Header which is also 1...*
rest of the fields are elements as 1..1
Now I need to convert this into Flat file using Receiver File Adapter, I gave this in my content conversion logic
recordset Structure -
MstHeader,BFKKZK,BFKKZP
MstName.addHeaderLine     0
MstName.fieldFixedLengths     8
MstName.endSeparator     'nl'
Header.addHeaderLine     0
Header.fieldFixedLengths     30,10,15,6,6
Header.endSeparator     'nl'
Subheader.addHeaderLine     0
Subheader.fieldFixedLengths     34,10,35,16
Subheader.endSeparator     'nl'
But with this I am getting exception as -->
Could not process due to error: java.lang.Exception: Exception in XML Parser (format problem?):'java.lang.Exception: Message processing failed in XML parser: 'Conversion configuration error: Unknown structure 'ns0:MT_Test' found in document', probably configuration error in file adapter (XML parser error)'
I know that http://help.sap.com/saphelp_nwpi711/helpdata/en/44/686e687f2a6d12e10000000a1553f6/content.htm says following -->
The expected XML structure contains the structure as nodes filled with any number of elements without additional subnodes.
But does that mean Structure with sub-nodes cannot be converted in flat format.
Pls. suggest the solution for this.

I resolved the issue & able to convert the hierarchical XML file into flat file with the desired format I wanted.
Rather then FCC, I use MessageTransformBean module and I have to insert more dummy contexts & dummy fields in the target structure in order to achieve the flat file format.
I am getting file ( not actual file below just template is shown below) like this now
Header1 ....details....
SubHeader1.1
SubHeader1.2
SubHeader1.x
Header2 ....details....
SubHeader2.1
SubHeader2.2
SubHeader2.x
Headerx ....details....
SubHeaderx.1
SubHeaderx.2
SubHeaderx.x
Once the total development is over on my side I will create the blog for this. So this following statement is only correct when you use protocol as FCC but not with module.
"The expected XML structure contains the structure as nodes filled with any number of elements without additional subnodes."
