Query another message payload from graph mapping program

Question

Hi all,
I have the following scenario
Third Party Business System -> XI -> ECC 5.0
Third Party sends ORDER to ECC and ECC answers with ORDRSP
When mapping ORDRSP.ORDERS05 to Third Pty format, I need to use info that the Third Party provided us on the ORDERS.
So... I have to query the ORDERS message payload from ORDRSP message mapping program.
Any ideas?
My first idea deal with doing an RFC lookup to search the ABAP Database for this info (my ABAP background raises ) but I'd like to know if there is a more elegant and efficent way of doing this.
regards,

Hi,
Let's try again to explain myself with my poor english!
Time frame
A) TPart system sends order. XI maps to ORDERS.ORDER05 idoc and is forwarded to ECC.
B) In ECC users modify Sales order and then triggers the outbound ORDRSP.ORDERS05.
C) XI has to map ORDRSP.ORDERS05 and include some info (in fact the original message) that was sent in step B).
The xmls from TPart could be (simplified version):
Orders (step A)
<?xml version="1.0" encoding="iso-8859-1">
<document>
  <header>
  </header>
  <Items>
  </Items>
  <Items>
  </Items>
  </Header>
</Document>
The received XML on step C) could be something like this:
<?xml version="1.0" encoding="iso-8859-1">
<Document>
  <PurchaseOrder_from_vendor>
  <i>Here I have to include the whole xml sent in step A</i>
  </PurchaseOrder_from_vendor>
  <SalesOrder_from_customer>
  <i>Here the ORDRSP.ORDERS05 mapping stuff</i>
  </SalesOrder_from_customer>
</Document>
All the communication will be always async.
Any ideas?
