Free order of tags when deserialising XML-data using Simple Transformatiosn

Question

Hi everybody,
I'm consuming a WebService and get something like this XML-data in the response:
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<getSalesResponse>
  <getSalesReturn href="#id0"/>
</getSalesResponse>
<multiRef id="id0">
  <customer href="#id1"/>
  <salesOrg href="#id2"/>
  <salesRecord soapenc:arrayType="SalesRecord[2]" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">
   <salesRecord href="#id3"/>
   <salesRecord href="#id4"/>
  </salesRecord>
</multiRef>
<multiRef id="id1"><customer>124843</customer></multiRef>
<multiRef id="id2"><salesOrg>0001</salesOrg></multiRef>
<multiRef id="id3"><material>mat1</material></multiRef>
<multiRef id="id4"><material>mat2</material></multiRef>
</soapenv:Body>
</soapenv:Envelope>
</xml>
I've written a Simple Transformation: it fills  my fields i_customer, i_salesorg, i_mat1 and i_mat2 from this XML-Data from the content of the <multiRef>-tags. But only if the order is exactly like this:
<multiRef><customer><tt:value ref="I_CUSTOMER"/>
  </customer></multiRef>
<multiRef><salesOrg><tt:value ref="I_SALESORG"/>
  </salesOrg></multiRef>
<multiRef><material><tt:value ref="I_MATERIAL1"/>
  </material></multiRef>
<multiRef><material><tt:value ref="I_MATERIAL2"/>
  </material></multiRef>
However the WebService doesn't guarantee a certain order for the <multiRef>-tags. That means the salesOrg could be contained ahead of the customer.
In a next step I've tried to use the command '<tt:group>' that allows free order of the first two elements:
<tt:group>
<tt:d-cond frq="1">
  <multiRef><customer><tt:value ref="I_CUSTOMER"/>
    </customer></multiRef>
</tt:d-cond>
<tt:d-cond frq="1">
  <multiRef><salesOrg><tt:value ref="I_SALESORG"/>
    </salesOrg></multiRef>
</tt:d-cond>
</tt:group>
<multiRef><material><tt:value ref="I_MATERIAL1"/>
  </material></multiRef>
<multiRef><material><tt:value ref="I_MATERIAL2"/>
  </material></multiRef>
However the WebService doesn't guarantee any order for the <multiRef>-tags. That means the first material could be contained ahead of the customer.
How can I insert the lines for my materials into to <tt:group>-command? Actually the WebService could deliever n materials, so I tried this (but that didn't work any more):
<tt:group>
<tt:d-cond frq="1">
  <multiRef><customer><tt:value ref="I_CUSTOMER"/>
    </customer></multiRef>
</tt:d-cond>
<tt:d-cond frq="1">
  <multiRef><salesOrg><tt:value ref="I_SALESORG"/>
    </salesOrg></multiRef>
</tt:d-cond>
<tt:d-cond frq="*">
  <tt:loop name="tab" ref=".IT_MATERIALS">
   <multiRef><material><tt:value ref="$tab.MATERIAL"/>
     </material></multiRef>
  </tt:loop>
</tt:d-cond>
Any help would be greatly appreciated. My colleagues have already begun to leave the office because I look more and more frustrated...

I have some Interface Mapping questions I was hoping someone could help me with. As you know, my source is an XML File and my target is an OracleDB. I'll start with the "EFFECTIVEDATE" field which was automatically mapped when I added the Source and Target Datastores. As I previously mentioned, this caused an error "Target Column EFFECTIVEDATE: Data may be truncated: the target Column is smaller than the source Column". After looking further into it, would the problem be that the "EFFECTIVEDATE" datatype in the XML is "DATETIME" whereas the "EFFECTIVEDATE" datatype in the database is "TIMESTAMP"? If so, what would be the fix for this? Could I convert it in the Implemenation Mapping like so? -
CONVERT(MONEY.EFFECTIVEDATE,TIMESTAMP)
Would using that in the Implementation simply do the trick?
Anyway, moving onto some of the other TARGET fields...
-ACTIVITYGUID
This should be an automatically generated new GUID value. How could I implement this into the Implementation?
-TRANSACTIONGUID
I'll need to query some of the other tables in the database in order to get this value. Is this allowed in the Implemenation? Do I have to add said tables to the target somehow? Can I just query the other tables in the Implementation field using normal select statements, etc.? I'm a bit confused on how this would work...
-TYPECODE
This needs to be a fixed value of '01'. How do I simply do that in the Implementation?
The other fields will all be implemented similar to the above so those are the main questions I have for now. Any help would be appreciated.
Thanks again for your help.
