BRE – Non debatched message Issues

Hello, I am having a hard time trying to get this to work.  I am passing a non-debatched message to the BRE via the Call Rules Shape in the orchestration.  I want it to evaluate the ‘IF’ for a parent node and take action on child nodes.  It seems like BRE is updating all child records to the first value.

For example, if I had this schema:

<Hdr id=123 cust=TTT >
    <Addr loc=SS account=0 > </Addr>
    <Addr loc=SM account=0 > </Addr>
    <Order ID=1 count=3></Order>
</Hdr>
<Hdr id=124 cust=TTT >
    <Addr loc=SS account=0 > </Addr>
    <Addr loc=SM account=0 > </Addr>
    <Order ID=2 count=5></Order>
</Hdr>

In the BRE, it looks something like this…
IF
AND
    Hdr/cust = TTT
    Addr/loc = SS

THEN
    Hdr/Addr/account = GetPOAccountNum( Hdr/Order/ID )

The ‘GetPOAccountNum’ is a .NET class that looks up from SQL and returns the acct #

THE PROBLEM:
The results are the same and seem to match the first Hdr node.  I suspect it’s because of the BRE pattern matching and updates all matching nodes in one call??  I don’t won’t to debatch the message – Any Ideas?

Thanks
